From tomhend at u.washington.edu Thu Jan 1 00:30:03 2009 From: tomhend at u.washington.edu (tomhend@u.washington.edu) Date: Thu, 1 Jan 2009 00:30:03 -0800 Subject: [ns] ns-2 FAQ Message-ID: <200901010830.n018U3V5003187@ns-regression.ee.washington.edu> The Network Simulator ns-2: Frequently Asked Questions Note: This FAQ is now available at the project wiki: http://nsnam.isi.edu/nsnam/index.php/Ns_Users_FAQ _The mailing is is now subscriber only---please see the FAQ entry on "How do I post to the mailing list? Why was my post rejected?" for details._ * _Where do I get ns?_ From the ns web site at http://www.isi.edu/nsnam/ns/ns.html and the download page http://www.isi.edu/nsnam/ns/ns-tests.html. * _What platforms does ns run on and what kind of hardware do I need?_ Please see "where to start" on the building ns web page: http://www.isi.edu/nsnam/ns/ns-build.html#start. * _What should I do if I have trouble downloading/extracting ns?_ This question is answered in detail at http://www.isi.edu/nsnam/ns/ns-problems.html#downloading. * _What should I do if I encounter problems building ns?_ Check: 1. the README that comes in the distribution (very brief), 2. the "installation problems, bug fixes and help" web page http://www.isi.edu/nsnam/ns/ns-problems.html, 3. the archives of the ns-users mailing list http://www.isi.edu/nsnam/ns/ns-lists.html, 4. post a bug report (see below) http://www.isi.edu/cgi-bin/nsnam/reportbug.cgi. * _What do I do after I successfully build ns?_ + Put the path to your ns executable into your PATH environment + Put the path to your otcl into your LD_LIBRARY_PATH environment + Put the path to your tcl library into your TCL_LIBRARY environment * _Where can I find documentation for ns?_ All documentation is linked from the main ns web page http://www.isi.edu/nsnam/ns/. Documentation includes a tutorial (originally from Marc Greis) and a reference manual (ns notes and documentation). * _Words, words, words... that documentation is nice, but where are some sample scripts I can start from?_ Many sample scripts can be found in the ns distribution in ~ns-2/tcl/ex and ~ns-2/tcl/test. * _What protocols does ns support?_ A lot! Almost all variants of TCP, several forms of multicast, wired networking, several ad hoc routing protocols and propagation models (but not cellular phones), data diffusion, satellite, and other stuff. See the documentation (described above) for details, or download ns and look. * _How do I know that ns correctly implements these protocols?_ Ns has validation tests that cover many protocols, see http://www.isi.edu/nsnam/ns/ns-tests.html. However, ultimately users are responsible for verifying that ns is accurate for their purposes---since we cannot foresee all the ways ns may be used, we cannot test all cases with all inputs. * _Are there any contributed/additional protocols not in the main distribution?_ Yes, please see the contributed code web page http://www.isi.edu/nsnam/ns/ns-contributed.html. The mailing list archives can also be helpful (see below). * _How should I get started doing something (like implementing a new protocol or trying an experiment)?_ We recommend that you look through the tutorial (see documentation, above), then start with an example program that is most similar to yours (in the tutorial, or in tcl/ex or tcl/test in the distribution), and then start changing things. * _What should I do to compile ns to reflect my changes if I've modified some .cc or .h files?_ go to ns directory and run "make" or "make depend; make" * _How do I subscribe to the ns-users mailing list? How do I search old list archives? I can't take any more---how do I get off this list?_ To subscribe or unsubscribe, see http://www.isi.edu/nsnam/ns/ns-lists.html. The list archive is at http://www.isi.edu/nsnam/ns/ns-lists.html. * _How do I post to the mailing list? Why was my post rejected?_ As of June 2004 the ns-users lists allow posts from _subscriber only_. If you're not a subscriber, your posts to the list will be rejected. (This is unfortunately necessary to dispose efficiently of spam; manual filtering is too expensive.) We realize that the list is high traffic, so if you wish to post to the list without receiving messages on it, please subscribe and select the _no-mail_ option for your subscription. For details about the mailing list including mailing-list specific FAQ (for example, what if you're subscribed but still can't post), please see http://www.isi.edu/nsnam/ns/ns-lists.html. * _Did my post appear on the mailing list? (Or, why didn't my post appear on the mailing list?)_ See the http://www.isi.edu/nsnam/ns/ns-lists.html web page for help debugging mailing list problems. * _What if I have a question that's not answered here?_ If you've checked the installation problems and bug fixes web page (http://www.isi.edu/nsnam/ns/ns-problems.html) and there's no answer to your question, you may want to file a bug report or post a question to the ns-user's mailing list. First, you should check the archive of the list at http://www.isi.edu/nsnam/ns/ns-lists.html. Your question may already be answered there. If not, you can post a bug report using the web form at http://www.isi.edu/cgi-bin/nsnam/reportbug.cgi. If your question is NOT about ns implementation bugs, you may wish to post to the list. First you should subscribe. Subscription instructions are at http://www.isi.edu/nsnam/ns/ns-lists.html. _Please note that mail sent to the list is publicly distributed and archived. _If you have concerns about your message being made public (spam harvesting of your address), please consider that _before_ posting. We cannot remove messages from reciepient's mailboxes or the public archive after they're posted. When posting bug reports, please _always_ include information including at least (the bug report form includes spaces for these): + what version of ns you're using, + what operating system you're running on (not just Linux or Solaris, but RedHat version 7.0 or Solaris 2.4---send us the output of "uname -a"), + what specific behavior you see (if ns doesn't compile, what's the specific error; if TCP does something strange, what exactly did it do [send a pointer to a packet trace]), + what behavior you expected to see (if ns doesn't compile this is obvious, but if TCP does something strange, why is it strange, where is the TCP spec violated?), + pointers to your script detailed output files, + a statement that "yes, I've read the FAQ, ns-problems page, and manual and I couldn't find the answer there" (or a statement about why you didn't do that yet :-) Soo-Hyun Choi observed from posts to the list: _Sometimes, I see this list is filled with the questions with: 1) asked many times before 2) hardly understandable what this guy is asking 3) too easy to find an answer over a few clicks over the Internet 4) soliciting to do their homework in a simple way by asking in this list 5) easily seekable an answer by contributing a couple of hours of reading the ns-manual 6) etc, etc. _ _As many of us in this list are doing an advanced degree, it would be suggested to read the following article in order to raise a useful/meaningful question in a smart way. http://www.catb.org/~esr/faqs/smart-questions.html _ This is _very_ good advice, since asking the Right Question is very likely to get a good/helpful answer, while asking a question poorly. For example, think about how you would answer these two questions: _"Ns doesn't work for me, it crashes. Help."_ as compared to _"I get a segmentation fault when running test script test-suite-webcache on Mandrake 10 Linux. The backtrace is on my web page at www.someu.edu/~someone. It looks like it passes in the on-line test suites, but it fails for me. Am I doing something wrong?_ A reminder about mailing list etiquette: + Please check the web pages and list archives before posting your question. + Please keep the body of your post to simple ASCII, not HTML. + Please do _not_ send large attachments (if what you have is bigger than a few kilobytes, put it on a web page and send a URL) + Before posting a question like "did people see my post" or "the list seems down", please check the archives (you can answer this question more accurately by checking yourself rather than asking). + Please don't post subscribe/unsubscribe requests directly to the list, use the lists' information page. (see the web page mentioned above for details).

Message-ID: Hi all, currently I am working on address allocation in MANET. for that I was implementing an addressing agent MANETconf, which works above routing protocol. As part of simulation scenario I need to simulate departure of node so a node does not participate in packet forwarding. I tried $node_(i) reset but it doesn't work. can any one suggest me how to stop a node(or disable routing agent on a node)?

From phenix_yw at hhu.edu.cn Mon Jan 5 22:19:17 2009 From: phenix_yw at hhu.edu.cn (Phenix) Date: Tue, 6 Jan 2009 14:19:17 +0800 Subject: [ns] (A naive solution) how to set different transmit range for different node References: <430881430.19092@eyou.net> <430949739.22788@hhu.edu.cn> <431036815.27991@eyou.net> <431211429.13128@hhu.edu.cn> Message-ID: <431220632.19781@eyou.net> Hi All, After hacking threshold.cc, I've known the formula used to calculate receive threshold (ATTENTION: threshold.cc only generates RXThresh_, NOT Pt_). I modified TwoRayGround formula in threshold.cc, as below : Pr * d^4 * L Pt = --------------------------- Gt * Gr * (ht^2 * hr^2) Pr is replace with RXThresh_ whose value is 3.652e-10. If a distance is given, Pt can be calculated by above formula. e.g. Tx Range Pt_ 100m 0.00721383 150m 0.03652 200m 0.115421 250m 0.28179 300m 0.58432 ... ... I attached modified threshold.cc renamed threshold_Pt.cc . After compiling it, you can use like this: ./threshold_Pt -m TwoRayGround But unluckily, if the tx range is smaller than crossover_dist (always should be 86.1425m), the generated Pt_ value is incorrect either using Friis or TwoRay. If you know why, please let me know. I've developed a simple tcl script in order to validate transmit range with different Pt_ value. I attached this script named TxRangeTest.tcl. The routing protocol used in the script is MFlood, which is just a simple flooding algorithm. Trace format has been changed a little, like: s 1.000000000 1 1.00 200.00 AGT --- 0 cbr 512 [0 0 0 0] ------- [1:0 0:0 32 0] [0] 0 0 r 1.004860003 0 0.00 200.00 AGT --- 0 MFlood 532 [mflood 1.000000000 1.00 200.00 ] The trace format of cbr packet can be referred to NS2 manual. The explain of trace format about MFlood packet is below: event = $1; curr_time = $2; curr_node_id = $3; curr_position_x = $4; curr_position_y = $5; trace_type = $6; pkt_seq = $8; pkt_type = $9; pkt_generate_time = $12; prev_hop_position_x = $13; prev_hop_position_y = $14; Finally, a AWT file is used to calculate the transmit range. #======================================================================== BEGIN { RecvNum = 0; final_curr_position_x = 0; final_curr_position_y = 0; final_prev_hop_position_x = 0; final_prev_hop_position_y = 0; } { event = $1; curr_time = $2; curr_node_id = $3; curr_position_x = $4; curr_position_y = $5; trace_type = $6; pkt_seq = $8; pkt_type = $9; pkt_generate_time = $12; prev_hop_position_x = $13; prev_hop_position_y = $14; if ( event == "r" && curr_node_id == 0 && trace_type == "AGT" ) { RecvNum++; # printf(" %3d [Time : %f] N0(%.2f,%.2f) <---- N1(%.2f,%.2f)\n", # RecvNum, # curr_time, # curr_position_x, # curr_position_y, # prev_hop_position_x, # prev_hop_position_y); final_curr_position_x = curr_position_x; final_curr_position_y = curr_position_y; final_prev_hop_position_x = prev_hop_position_x; final_prev_hop_position_y = prev_hop_position_y; } } END{ dx = final_prev_hop_position_x - final_curr_position_x ; dy = final_prev_hop_position_y - final_curr_position_y ; tx_range = sqrt(dx * dx + dy * dy) ; printf(" \nNum of Recv pkts : %d \n", RecvNum); printf(" \nTx Range of Node 1: %f \n", tx_range); } This is just a reference. You should do some changes according to your trace file if you use other routing protocol.

Answer: In ns2.26 and ns2.27, you can change (basicRate_ and dataRate_ ): Mac/802_11 set basicRate_ 1Mb Mac/802_11 set dataRate_ 11Mb in your tcl script. FHSS (IEEE802.11) Mac/802_11 set SlotTime_ 0.000050 ;# 50us Mac/802_11 set SIFS_ 0.000028 ;# 28us Mac/802_11 set PreambleLength_ 0 ;# no preamble Mac/802_11 set PLCPHeaderLength_ 128 ;# 128 bits Mac/802_11 set PLCPDataRate_ 1.0e6 ;# 1Mbps Mac/802_11 set dataRate_ 1.0e6 ;# 11Mbps Mac/802_11 set basicRate_ 1.0e6 ;# 1Mbps DSSS (IEEE802.11b) Mac/802_11 set SlotTime_ 0.000020 ;# 20us Mac/802_11 set SIFS_ 0.000010 ;# 10us Mac/802_11 set PreambleLength_ 144 ;# 144 bit Mac/802_11 set PLCPHeaderLength_ 48 ;# 48 bits Mac/802_11 set PLCPDataRate_ 1.0e6 ;# 1Mbps Mac/802_11 set dataRate_ 11.0e6 ;# 11Mbps Mac/802_11 set basicRate_ 1.0e6 ;# 1Mbps Note: -if using the short preamble option: you can change the line as: Mac/802_11 set PreambleLength_ 72 - # frequency is 2.4 GHz Phy/WirelessPhy set freq_ 2.4e+9 # transmit power Phy/WirelessPhy set Pt_ 3.3962527e-2 # Receive sensitivity.

If you want setup a specific range, use the program ~/indep-utils/propagation/threshold.cc to obtain the desired RXThresh_ (rx sensitivity) based on the above frequency, transmit power and your desired range. 802.11g: #define DSSS_CWMin 15 #define DSSS_CWMax 1023 #define DSSS_SlotTime 0.000009 #define DSSS_CCATime 0.000003 #define DSSS_RxTxTurnaroundTime 0.000002 #define DSSS_SIFSTime 0.000016 #define DSSS_PreambleLength 96 #define DSSS_PLCPHeaderLength 40 #define DSSS_PLCPDataRate 6.0e6 // 6Mbps #define DSSS_MaxPropagationDelay 0.0000005 // 0.5us Note: bandwidth is different with achievable throughput. - In NS ACK are always sent at 1Mbps - NS use always the long PLCP preamble format sent at 1Mbps - by default NS uses RTS/CTS handshake - Packet's size has also an impact in the % of overhead.

I could not find the instproc init {} procedure of Agent/TCP/Reno or any of the other TCP Agents. Why? Is it because they inherit in a virtual way from class TCPAgent?, and so the instproc init {} procedure of the class TCPAgent is called only once for each of them. Then how do we differentiate between the creation of the different TCPAgents from only one instproc init {} procedure of class TCPAgent. My main objective is to pass arguments to the new Agent/TCP/Reno command which will pass the arguments to its respective init procedure (which I cannot find) and then the arguments will be passed to its static class constructor in the tcp-reno.cc file so i can choose whether or not to pass an argument to the constructor of the actual class RenoTcpAgent. The main idea is to add one more constructor to class RenoTcpAgent and then to be able to choose which constructor to call when creating the object from the tcl script like set tcpreno [new Agent/TCP/Reno]. So i thought i would do it by passing an argument like set tcpreno [new Agent/TCP/Reno arg1]. Any help, advice or suggestions for the above problem, or achieving a solution of some kind will be appreciated. Many thanks in advance.

Event bittorrent is already an alternative to content distribution in MANETs. In a general way, TCP isn't so good to MANETs because the overhead in handshakes and the well-known problem of delays and packet loss be interpreted by TCP as congestion. So, TCP will reduce the next window to avoid the supposed "congestion". Recently, my work was develop a multicast content distribution protocol to MANETs. I used UDP and the results were good. It'll apear in IEEE WCNC (in April). I'll add It to the contribution section of NS-2 Wiki. Take a look in there to see what is already avaiable.

How should I deal with broadcast in which scenario only one node send packets and all of the others receive. Waiting for your help. Thanks !

Message-ID: Hello everybody, I am trying to simulate a hand over. Following script shows two nodes (acting as AP) and a node moving within their vicinity. After a certain amount of simulation time, node 0 gets out of range of node 1 (AP) and stops sending packets. This is the point it needs to get associated with node 2 (another AP).

I generated aprox. 7000 events in a TCL source file and a lot of those events when given to the scheduler are lost. This is a code snippet: void ProtName::create_Pkt(Packet* p){ /* * Create a packet with source and destination header */ // Schedule it for later Transmission Scheduler::instance().schedule(target_, p2, 0.0); } Using printf's i can see the Scheduler correctly receives the packet, but later on there is no other trace of it. Any suggestions? Is there a limit to the events the scheduler can handle?

Message-ID: <7f61906e0901142142s300419ces88d114c04f59aeb2@mail.gmail.com> Dear all, I followed the instructions from R.Aguero et al., "Adding Multiple Interface Support in NS-2" to set up a multichannel simulation model (document, http://personales.unican.es/aguerocr). I think there is a major flaw of this method (or the NS2 is not suitable for multichannel): the multi wireless channels are not properly isolated. When a packet is sent from one node to other nodes, wireless-channel will check the nodes affected and send a copy of the packet to all the network interfaces linked to the affected node. This will block each network interface, which should only listen to the neighboring network interfaces tuned on the same channel. When capture effects are considered, such as in the more accurate mac model mac-802_11Ext and wireless-phyExt, this problem will become more salient. More comments and resolutions are heartily welcome.

I'm testing the effects of 802.11e parameters on collision rate, loss rate, throughput and average delay as network load increases. My topology is static with the nodes randomly positioned and a random node starts 1 flow of each priority level (total 4) every 20s of simulation time (total 14x4). I was trying to test topologies with 10, 30 and 50 nodes. With 10 nodes, I've got no problem at all in all scenarios I ran. However, simulations that generate higher throughput in scenarios with 30 and 50 nodes consume so much memory that it can't finish. I get: terminate called after throwing an instance of 'std::bad_alloc' what(): St9bad_alloc So, comes one of my doubts: how scalable is this code? What's the maximum number of nodes or flows I can have? What have you tested? I tried removing the headers I'm not using and all that stuff for running large simulations but I still get this error. Besides that, I've got some errors when running the simulations with 30 and 50 nodes with CFB enabled: ns: mac/802_11e/mac-802_11e.cc:80: : Assertion `dh->dh_fc.fc_type == 0x01' failed. This occurs when the packet that is to be transmitted in the function below is a data packet and not a control packet. inline void Mac802_11e::transmit(Packet *p, double t) { /* * If I'm transmitting without doing CS, such as when * sending an ACK, any incoming packet will be "missed" * and hence, must be discarded. */ if(rx_state_ != MAC_IDLE) { struct hdr_mac802_11e *dh = HDR_MAC802_11E(p); assert(dh->dh_fc.fc_type == MAC_Type_Control); assert(dh->dh_fc.fc_subtype == MAC_Subtype_ACK); assert(pktRx_); struct hdr_cmn *ch = HDR_CMN(pktRx_); ch->error() = 1; /* force packet discard */ } . My doubt is: when CFB is enabled, data packets may be transmitted without doing CS too, right? If so, assert shouldn't check just if p is a control packet but if it is a data packet too. I'd really appreciate your advice here. Other error I've got was: ns: mac/802_11e/mac-802_11e.cc:1107: : Assertion `pktTx_[pri]' failed. void Mac802_11e::RetransmitDATA(int pri) { struct hdr_cmn *ch; struct hdr_mac802_11e *mh; u_int32_t *rcount, *thresh; assert(mhBackoff_.backoff(pri) == 0); assert(pktTx_[pri]); assert(pktRTS_[pri] == 0); ch = HDR_CMN(pktTx_[pri]); mh = HDR_MAC802_11E(pktTx_[pri]); ... Does this mean that the packet that should be retransmitted doesn't exist?? Thank you very much for your help.

Any node receives a packet in the network layer by a method called RECV(). recv() decides what to do with the received packet. So the main parameter is the packet pointer itself. It reads the headers and decides discard that packet, forward it or send to upper layers. This is what a routing protocol does. In a choosed protocol, in the code fragment where It decides to forward a packet, change the code and add your packet manipulation.

row Message-ID: <6137c4f9cc169fd01c1b6a6d21a38e63.squirrel@webmail.c3sl.ufpr.br> It is like the following: There are two kinds of nodes: The sink and the rest. The sink, in a initial phase, will send many broadcast messages, gradually increasing its transmission power, so that every node will be able to determine its necessary TP in order to reach the sink. Thus, I intended to create a loop, where the messages would keep being sent, just increasing the TP. 64 if (strcasecmp(argv[1], "pot_setup")==0) { 65 Packet* pkt = allocpkt(); 66 hdr_myunequal* hdr = (hdr_myunequal*) hdr_myunequal::access(pkt); 67 hdr_cmn *cmh = HDR_CMN(pkt); 68 for (i=0;i<255;i++) { 70 hdr->type=INCR_POT; 72 cmh->addr_type()= NS_AF_INET; 73 cmh->prev_hop_ = myaddr; 74 cmh->direction()= hdr_cmn::UP; 75 cmh->next_hop()= IP_BROADCAST; 76 send(pkt,0); 77 } 78 return TCL_OK; 79 } Something similar to this, but with the increasing TP operations and a possible delay inside it. My doubts: 1 - Why this function, when called from inside the tcl script, results in a stach smashing? The packets must be reallocated in every iteration? 2 - How do I create a delay inside my C++ code, as part of a protocol operation? I had tried previously with the sleep and usleep commands, but in the end the code had been successfully compiled and no delay occured at all.

What you can do is simulate a wireless ad hoc network in ns and designate (logically) some of the nodes as gateways. As regards routing protocols, existing ad hoc routing protocols such as DSR and AODV are already available in NS and have been used as protocols for mesh networks. ? For mesh specific routing protocols, you will have to implement them. ? regards. --- On Wed, 1/21/09, zied naas wrote: From: zied naas Subject: [ns] Wireless Mesh in NS-2 To: ns-users at ISI.EDU Date: Wednesday, January 21, 2009, 2:29 AM hi I intent to simulate a WMN based 802.11 using NS2.

Pcap/File Network Objects These objects are similar to the Pcap/BPF objects, except that network data is taken from a trace file rather than the live network. As such, the notion of promiscuous mode and the naming of a particular interface (available to the BPF objects) are not available for the file objects.

Pt_ defines the amount of power transmitted from the antenna (Phy/WirelessPhy), and thus; it defines (together with the RXThresh_ parameter) the range of the mobile-node. And it is not used by the energy model. txpower defines how much power a mobile-node, as a whole, consumes when it is transmitting, and it is the one used by the energy model. For example; the PRO/Wireless 3945ABG card on my laptop can consume a maximum power of 1.8 Watt while transmitting and a maximum of 1.4 Watt while receiving. But the maximum transmitting power is 15 dBm ( ~ 31 mW) ! -- Waleed Tuffaha On Wed, Jan 21, 2009 at 7:07 AM, manish chaturvedi wrote: > > Hi, > > I am trying to incorporate energy model in my NS2.33 simulation.

Its initial implemention was done in tinyOS, and that is why I need to simulate its available transmission powers. There is a range of 255 possible ones in tinyOS, and I would like to change the NS variables (Pt_ [Transmit Power], CPThresh_ [Collision Threshold], CSThresh_ [Carrier Sense Power], RXThresh_ [Receive Power Threshold]), so an approximate behavior could be simulated. I do know the power consumption in mA and the Pout in dBm for each one of these 255 possible powers.

What you have to do is that, in the cmu trace file, where energy module is given, just write a condition that if simulator time is 100 secs, then print the trace in the trace file or you can declare a timer over there which will expire as per your desire. Each time when it will expire, it will print the energy values in the trace file.

Message-ID: <7f61906e0901242137v631f129eua376f49c640c0d96@mail.gmail.com> Sorry, I don't know why this email was rejected automatically. Send again Hello Ram?n, Thank you very much for your reply. I think discussion is good for our works. And I'm sorry to reply late for I'm concentrating on the coding and debugging work recently. I also noticed the "if(rifp->channel() == this) {" , but this appears in "if (GridKeeper::instance()) {}" branch only, in the "else{}" branch (using the list improvement) this decision should be added to make sure the channel is the same. It seems more like a bug when multichannel is adopted. It must be noted that What I used is ns2.33-allinone, and the codes mentioned above appears in ns-2.33/mac/channel.cc, the wirelessChannel Class's sendUp function. This version of 802.11, a great work provided by Qi Chen, Felix Schmidt-Eisenlohr, and Daniel Jiang, is more correct because it considers the wireless channel characteristics: a packet transmitted on one channel will probably block the receiving of another packets when its detected power is large enough. In this sense scheduling each packet onto all the channels without discrimination is not proper. I think you used the gridkeeper, which may be of no problem. But if not, when list-based improvement is used, there is another problem: the mobilenode class, (in /common/Mobilenode.cc\h, can not support multi-channel nodes lists because it has only one set of node list pointers: .... /* For list-keeper */ MobileNode* nextX_; MobileNode* prevX_; ... This will cause the sending of packets from wireless channel to Phy objects incorrect. Perhaps some users have noticed this problem too. I wish to see more comments who are working on multichannel simulations. Thank you very much.

I am running it on Cygwin on Windows Vista. After running Cygwin, we need to set environment variables before ns2 commands can be run. Alternatively, we can set them in ..bashrc file so that the environment variables for ns2 are automatically set each time when Cygwin is run instead of manually entering them on command line. When I add the environment variables path in .bashrc files, it gives an error when Cygwin starts saying that ns2-allinone-2.33-2.33 not fount. The commands work fine on the Cygwin prompt. Also Cygwin appends an extra 2.33 at the end automatically when giving an error. Here is the code for updating the environment variables in .bashrc file.

Here's the deal : im trying to simulate a WSN with nodes that are not mobile. In a topology.tcl file i have the nodes coordinates stored in the following form: $node_(0) set X_ 60 $node_(0) set Y_ 0 $node_(0) set Z_ 0 $node_(1) set X_ 92 $node_(1) set Y_ 43 $node_(1) set Z_ 0 ... Although i have these coordinates in the tcl files i still need to access them in C++, the reason is because i wanted to find distances between nodes as well as whether some nodes lied in the range of other (so its a couple of loops in C++) so id need something that look like this: for(i=0 ; i: > Hello Mathiew, > > Sorry for the late reply.

You can see that at the begining of the simulation, the page sizes are equal, but after a few seconds, maybe, the size pages are different. why?. the NS-2 web traffic module models the web traffic interaction as realistics as it's possible, and it's modeled such Statistical distributions, and some of them depend of the time. So, if you use different TCP protocols (for example, RENO) , with different timers, different handle of packets, maybe, some packets will arrive at web server at different times that if you use the other TCP protocol (for example, CUBIC). So, it's produce different web server responses (maybe with different size), and this page will produce different behaviour at client node, and so on... Conclussion: it's imposible to compare the same trace with both protocols..... at least...

I added a piece of code to one of the c files and intentionally added an error to see whether ns2 was registering it or not. After doing "make clean" --> "configure" --> "make", no error appeared, as if i hadn't added anything. Giving it a closer look, it seemed that the .o files weren't being cleaned at all. Although the version was working fine a couple of days ago, no it isnt. Does Anyone know why, and how it could possibly be fixed. Thanks.

For example, you have a network of 100 nodes, then you can control the number of nodes, let's say each node can have 10 neighbors or each node can have 20 neighbors. To achieve this, you can vary the grid size and random placement of nodes in the grid. Second this is that, have you declared the node location in your tcl script or load any coordinate file for the nodes? If you won't do this, ns2 will consider that each and every node is the neighbor of each other. So, consider this also.

I have 2 users and I trace the size of the windows of each (cwnd_). I think that the sum of this two window size exceeds the capacity there have to be an event of dropping a package. In this case, using TCP, I have an ?dupack_action? or a ?timeout?. However, there are situations where the sum of the size of the windows of the 2 users (cwnd1 + cwnd2) does not exceeds the capacity and I still have an event of dupack_action. Do someone know why happened the following situation? How the NS2 uses the queue to drop a packet even the sum is not over the maximum capacity of the network?

What he answered specifically is how to calculate the distances between to nodes, which uses the coordinates of the nodes by accessing them from struct mb_node in file God.cc (in ./mobile). After retrieving the nodes coordinates i think it becomes an easy task to pass them to the MAC layer. I also found the same solution that Keven proposed at this link: http://www.cse.msu.edu/~wangbo1/ns2/nshowto2.html Below i will paste Keven's original reply. I hope it turns out useful. Cheers, Mathiew ------------KEVIN'S REPLY-------------------- Hi Mathiew I needed to the same in my project. what I did is used god object. you can study and you can do many more things using it . here I am just describing what I did: I added following function in ns-2.33/mobile/god.cc (you will need to add declaration in god.h) double God::getdistance(int i,int k) { double x1=mb_node[i]->X(); double y1=mb_node[i]->Y(); double x2=mb_node[k]->X(); double y2=mb_node[k]->Y(); double distance; distance=sqrt(((x1-x2)*(x1-x2))+((y1-y2)*(y1-y2))); return distance; } then I was able to get distance between two nodes by writing following code in c++ God::instance()->getdistance(i,k); // i and k are the id of the nodes you will also need to include following statements in your .tcl file 1 after creating topography set topo [new Topography] $topo load_flatgrid $val(x) $val(y) set god_ [create-god $val(nn)] 2. when you are dynamically creating nodes for { set i 0 } { $i < $val(nn) } { incr i } { set node_($i) [$ns_ node $i] $node_($i) random-motion 0 ;# disable random motion $god_ new_node $node_($i) } following is a function of my agent for your reference: void Manetconf::neighbors(int i) { int nodes=God::instance()->nodes(); cout<<"neighbors of node "<IsNeighbor(i,k)) cout<getdistance(i,k)<<" yes"<getdistance(i,k)<<" no"< hi Mathiew > > I have exactly same as your problem.

Please help. Message-ID: <17265.77814.qm@web55807.mail.re3.yahoo.com> Hi. I implementing a new application layer protocol over the nsis module on ns- 2.29. I am running the tcl scripts now, and I am having a problem while setting up the nodes in the following manner using for loop: #Nodes for {set i 1} {($i) <= 2} {incr i} { set n($i) [$ns node] set udp($i) [new Agent/UDP] $ns attach-agent $n($i) $udp($i) set tcp($i) [new Agent/TCP/SimpleTcp] $ns attach-agent $n($i) $tcp($i) $tcp($i) set fid_ 0 $tcp($i) listen set app($i) [new Application/TcpApp/GistTcpApp $tcp($i)] set gist($i) [new Application/Gist] $gist($i) attachAgent $udp($i) $app($i) setapp $gist($i) $gist($i) pbs-install } #Links $ns duplex-link $n1 $n2 1Mb 100ms DropTail $ns duplex-link-op $n1 $n2 orient right This is giving the following error when I try to send any packets from node n1 to n2. can't read "n1": no such variable while executing "$ns duplex-link $n1 $n2 1Mb 100ms DropTail" But if I initialize the n1 and n2 separately without use of for loop, the script is running fine. Without for loop the initialization is as follows: set n1 [$ns node] set udp1 [new Agent/UDP] $ns attach-agent $n1 $udp1 set tcp1 [new Agent/TCP/SimpleTcp] $ns attach-agent $n1 $tcp1 $tcp1 set fid_ 0 $tcp1 listen set app1 [new Application/TcpApp/GistTcpApp $tcp1] set gist1 [new Application/Gist] $gist1 attachAgent $udp1 $app1 setapp $gist1 $gist1 pbs-install set n2 [$ns node] set udp2 [new Agent/UDP] $ns attach-agent $n2 $udp2 set tcp2 [new Agent/TCP/SimpleTcp] $ns attach-agent $n2 $tcp2 $tcp2 set fid_ 0 $tcp2 listen set app2 [new Application/TcpApp/GistTcpApp $tcp2] set gist2 [new Application/Gist] $gist2 attachAgent $udp2 $app2 setapp $gist2 $gist2 pbs-install Kindly help me out. What am I doing wrong in case of the for loop? Thanks in anticipation.
