I had experienced a lot of problems trying to make these changes on the mac-802_11.h in the newer releases of ns-2.26 and ns-2.27: they did not worked for me. I had to modify the sources of mac-802_11{.cc,.h} in an additional way. In addition to set the macros, I had to override some inline functions defined at the .h file. Here I paste the modifications. They were suggested because the inline methods of PHY_MIB took the parameters from other place than the defines (the defines were not used at all, annoyng but true). You can check that it is true by looking at the commented-out code I submit as well: they do not have any "DSSS" prefix: // This is 802.11g #define DSSS_CWMin 15 #define DSSS_CWMax 1023 #define DSSS_SlotTime 0.000009 // 9us #define DSSS_CCATime 0.000004 // 4us #define DSSS_RxTxTurnaroundTime 0.000002 // 2us #define DSSS_SIFSTime 0.000010 // 10us #define DSSS_PreambleLength 74 // 74 bits => Preamble of 120 bits #define DSSS_PLCPHeaderLength 26 // 26 bits #define DSSS_PLCPDataRate 6.0e6 // 6Mbps /* Must account for propagation delays added by the channel model when * calculating tx timeouts (as set in tcl/lan/ns-mac.tcl). * -- Gavin Holland, March 2002 */ #define DSSS_MaxPropagationDelay 0.000002 // 2us XXXX class PHY_MIB { public: PHY_MIB(Mac802_11 *parent); //Modified by GViso // inline u_int32_t getCWMin() { return(CWMin); } // inline u_int32_t getCWMax() { return(CWMax); } // inline double getSlotTime() { return(SlotTime); } // inline double getSIFS() { return(SIFSTime); } // inline double getPIFS() { return(SIFSTime + SlotTime); } // inline double getDIFS() { return(SIFSTime + 2 * SlotTime); } // inline double getEIFS() { // // see (802.11-1999, 9.2.10) // return(SIFSTime + getDIFS() // + (8 * getACKlen())/PLCPDataRate); // } // inline u_int32_t getPreambleLength() { return(PreambleLength); } // inline double getPLCPDataRate() { return(PLCPDataRate); } // inline u_int32_t getPLCPhdrLen() { // return((PreambleLength + PLCPHeaderLength) >> 3); // } inline u_int32_t getCWMin() { return(DSSS_CWMin); } inline u_int32_t getCWMax() { return(DSSS_CWMax); } inline double getSlotTime() { return(DSSS_SlotTime); } inline double getSIFS() { return(DSSS_SIFSTime); } inline double getPIFS() { return(DSSS_SIFSTime + DSSS_SlotTime); } inline double getDIFS() { return(DSSS_SIFSTime + 2 * DSSS_SlotTime); } inline double getEIFS() { // see (802.11-1999, 9.2.10) return(DSSS_SIFSTime + getDIFS() + (8 * getACKlen())/DSSS_PLCPDataRate); } inline u_int32_t getPreambleLength() { return(DSSS_PreambleLength); } inline double getPLCPDataRate() { return(DSSS_PLCPDataRate); } inline u_int32_t getPLCPhdrLen() { return((DSSS_PreambleLength + DSSS_PLCPHeaderLength) >> 3); } The rest remain the same (As I remember ... :-)) Next is to make "make depend;make" at the ns-2.27 directory.

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. * _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.

Message-ID: <1080828943.3e43483cyandao@myrealbox.com> Hi, My intention is for a MessagePassing Agent to receive data from another agent, and then to pass the data to an application attached to it for processing, and then to have the result of the processing sent back to the Agent. In the messpass.cc file, there's a recv() method which defines such procedure in "if(app_) then process_data". But from the test suite simulation script test-suite-message.tcl, there's already a Flooding subclass method "recv" which overrides the parent method, so the message will actually be passed back to the Tcl side. (this is how I understand it) I tried removing the "recv" definition in the Flooding subclass, but the simulation comes up with errors "invoked from within", so I guess it cannot be deleted? My questions are: 1. Is there a way to get a list of neighbour nodes in the C++ side? In OTcl, you can use "$node_ neighbors", how abt in C++? If it can be done, then I can write the Agent definition in C++ side. 2. Otherwise, is there a method to pass data from Agent to its attached Application in OTcl side? And to receive data from the Application too?

I think you should check for the version numbers. Patches don't apply if versions are too different. Also check if the patch is a "good one", that is some patches have an incompatible notation of files to be patched - I had the experience. Look in the patch for, e.g., diff ...blah blah... --- dir1/file1.cc +++ dir2/file1.cc If dir1 != dir2 you may have some difficulties to patch the file - some old implementations of diff/patch did so in older times... If so, you will have to replace the second dir name with the first, supposing the structure of the directories in the different versions to be patched has not changed a lot...

The timestamp_ field in the packet common header is set (as far as I know) by an Agent with the aim of measuring packet delays. In fact in apps/udp.cc it is used as follows: hdr_cmn::access(p)->timestamp() = (u_int32_t)(SAMPLERATE*local_time); where local_time is Scheduler::instance.clock(). I don't think there is anything wrong with filling the timestamp_ field with something different, which may be more useful to you. Regards, C.

Message-ID: <7E0971A9071A42458BD22F374AA889F5F76652@bgsmsx402.gar.corp.intel.com> I am using TKN's .11e extensions to NS2. I am trying to get results similar to what is reported in the report/paper - I am using UDP traffic (CBR) with different rates and intervals. I am not seeing the same behavior with regard to the throughput as the number of stations increase (the throughput goes down after 8/9 stations, the paper/report says at least 14 stations before throughput decreases. Anyone has any idea about this? Please let me know. Can anyone please send me any scripts that might have worked for those results? If I can run those & see the same results it might be quicker rather than get to the right parameters myself. I am trying to simulate voice & data traffic over .11e.

And you have your node with two interfaces; but you must to make changes (in ns-mobilenode.tcl) depending of the interfaces type (if they are iqual or not)and in the routing protocol too.

I have been using ns-2 for simulating a network with 2 nodes, link bandwith of 100mbps and delay 10ms. I have specified node0 as sender with TCP protocol agent attched to this node and node1 as the sink . we have defined the traffic source packetsize( ftp traffic source) as 500bytes but , after simulation we get the packet size as 1040 bytes. PLease tell us how we could vary the packetsize in our program? whether we could include packets of different packetsizes in the same program? how can we determine link utilisation using trace files or any other method? how should we simulate WAN networks? Do we have do specify other parameters for WAN or is it just simple simulation? can we find out the transmission time for packets of different sizes in the same program? thank you raji From xuanc at ISI.EDU Fri Apr 2 08:56:44 2004 From: xuanc at ISI.EDU (Xuan Chen) Date: Fri Apr 2 08:57:12 2004 Subject: [ns] Re: Re : Re: help about diffserv policy In-Reply-To: <20040402115509.27357.qmail@seu.edu.cn> Message-ID: yes, you should definitely consider it when you design those policies, but the diffserv does NOT.

I have installed ns 2.27 under cygwin. I put tcl-debug-2.0/ parallel to ns-2.27/ and configured with tcldebug giving the path and enabling the debugging, and examined Makefile to ensure tcl-debug options enabled. This is what I did step by step: make distclean configure --enable-debug --with-tcldebug=/../tcl-debug-2.0 make; make install Although everything works perfect up to this point debugger results with "script debugging disabled. Reconfigure --with-tcldebug and recompile". What does "Reconfigure --with-tcldebug and recompile" mean? Because configure --with-tcldebug ; make does not work for me.

In this protocol, I am using a session ID to identify each route, because even between the same source and destination, they may have different routes due to the different bandwidth requirement of traffic sources. And the data packet will use this session ID to find which route it will be sent or forward. But I couldn't figure out how to put this session ID in the data packet header, or where I should put the session ID to identify which route the data packet will send? I am using CBR as the traffic source. If anybody could help me out, I would really appreciate it.

The sources sending with 2Mbps CBR traffic with UDP agent (my channel bandwidth is 2 Mb) to the destinations. I calculated the loss based on the number of received packets at the destinations and number of sent packets from the MAC at the sources , as follows: Loss = (1 - packet received at the destination/number of packets sent form the MAC sublayer at the source) * 100%. When I count the number of sent packets (by greping them from the trace file), some of packet ID's and Sequence number are duplicated (because they are dropped at the destination due different reasons , for instant due to collisions. The MAC is required to retransmit them again based on the number of retry). In this case, Do I need to consider these duplicated packets in the number of sent from the MAC, since they are transmitted again and affected other parameters such as loss and delay,etc.... or considering only the number of sent as (Number of generated packets - number of dropped packets at the source).
