[ns] New MAC protocol
I have written a MAC protocol, and update some files like the packet.h and the ones that we usually update if we were writing a new agent. However when i wrote the corresponding TCL after I recompliled ns2 i get an error saying Mac/mymac undefined command!! Is there any special file i should update to make the tcl know that Mac/mymac is a new prtocol. I mean I wrote the static class in the c++ but how will the tcl find my protocol just by reading the command MAc/mymac. Isn't there a special file that ns2 searches in to know where the class Mac/mymac is in or something? Thank you very much..I urgently need an answer ASAP ~Samir Salman
Re: [ns] New MAC protocol
In your mymac.cc file, you need to define a Tcl class, say MacMyMacClass,
which is derived from TclClass. This class is in fact very simple, just to
let Tcl know that you have an object named Mac/mymac. After this, compiling
ns2 will do the rest of work and your Tcl code should understand your new
MAC protocol. The code is follows:
static class MacMyMacClass : public TclClass {
public:
MacMyMacClass() : TclClass(Mac/myMac) {}
TclObject* create(int, const char*const*) {
return (new MacMyMac(PMIB));
}
} class_mac_mymac;
Hope this helps.
Hai.

[ns] TCP congestion window - Problem
Hi, This may be simple, but I am wondering if TCP Reno is working fine in NS-2. I traced cwnd_ size, and it showed ssth like this: 0 cwnd_ 1.000 0.04cwnd_ 2.000 0.09cwnd_ 3.000 0.1 cwnd_ 4.000 0.15cwnd_ 5.000 0.15cwnd_ 6.000 0.16cwnd_ 7.000 0.16cwnd_ 8.000 0.2 cwnd_ 9.000 0.2 cwnd_ 10.000 0.21cwnd_ 11.000 0.21cwnd_ 12.000 0.22cwnd_ 13.000 0.23cwnd_ 14.000 0.23cwnd_ 15.000 0.24cwnd_ 16.000 0.27cwnd_ 17.000 0.29cwnd_ 8.000 0.37cwnd_ 8.125 1.37cwnd_ 1.000 1.42cwnd_ 2.000 1.47cwnd_ 3.000 1.52cwnd_ 4.000 1.53cwnd_ 4.250 1.57cwnd_ 4.485 1.58cwnd_ 4.708 1.6 cwnd_ 4.921 At the begining TCP reno is performing slow Start till 0.27 when loss is detected. What happened next is strange for me... Shouldn't it reduce it's sending rate to 1 and start slow start again? It seems as it would be trying to perform Fast Retransmit/Fast Recovery instead, but finally it reduces cwnd_ to 1... Could anyone explain it to me??

[ns] one sender-multiple receivers
Hello again, i would like to ask you, how can we send packets just from one node-source to miltiple nodes-neighbors. Can it be done trough UDP agents? or shall i determine my own routing protocol? thank you.
[ns] insert-entry - Node
Hi, I'm making a derived class of Connector. Now I need to use insert-entry method of Node to insert my class at the entry point of any node. What changes do I need to make inside tcl/lib/ files and common/ ? Best regards, Alexandre Malhão
[ns] Set bandwidth in mobile nodes...
Hi, I would like to know how to set the bandwidth in a wireless mobile simulation. I found many examples and now I don't know what I must use: MAC set bandwidth_ 2Mb; LL set bandwidth_ 2Mb; Rb = 2*1e6; // 2 Mb and after... [ bind(Rb_, Rb); ] Could somebody tell me what is the correct manner? I am doing simulations in mobile ad-hoc networks and I need to set the bandwidth of the communication to 2Mb. And I need to set the range to 250m too. Thanks in advance, Ricardo.
