[ns] How to access mac layer in c++ of ns2

[Daniel Dekst]

Hi,
   
  Yes, if we want to use mac functions, we first need to include mac header file
  #include<mac-802_11.h>
   
  But a problem is that we need to acquire the pointer of Class Mac802_11 so that we can access the variables or functions.
   
  For physical layer you want to know, it is easy.
  You can see in node.h it provides a list of phys, so if you acquire the pointer of the list, then you can use it.
  in your .h
  #include<mobilenode>
   
  in your Class
  MobileNode* node_;
   
  then in your .cc you can
  WirelessPhy* physicalLayer = (WirelessPhy*) (node_->ifhead()).lh_first;
physicalLayer->node_off();
   
  Best,
  Pei

    hi

As I know of, u can access the MAC layer, by declaring the mac header files where u want to use the mac functions. Similarly u should be able to use functions of any layer.

I wonder what is the idea behind your approach...plz tell more about it, as it looks ok to me, as well.

Hi, everyone,

I know how to access physical layer since Class Node provides a variable ifhead_ for list of phys.
So
WirelessPhy* physicalLayer = (WirelessPhy*)(node_->ifhead()).lh_first;
works.

But it does not provide list of mac, thus can I access mac layer similar as above?
I know tcl may work by calling mac layer and then again use tcl to return the desired value, but is there any method to access it directly using c++?

Best,
Pei
