[ns] Fwd: DSR implementation
Sir, Please tell me what classes have been used to implement the DSR protocol in ns2. For example the ping protocol has been implemented using class PingAgent : Public Agent struct hdr_ping static class PingClass, etc, etc... Please tell me the classes and the corresponding files which have been used to implement the DSR protocol. Also please send me any sample tcl code through which i could test the simplest DSR protocol implementation in ns2.

Re: [ns] Calculate Collisions in Wireless ad hoc networks
Hey, Have you thought about writing a script to do this calcuation (adding up) for you? There are plenty of AWK scripts out there that give good examples.

[ns] Calculate Collisions in Wireless ad hoc networks
Hi i want to calculate number of collisions in trace file. somebody told me to count simply COL in trace files. This is not appropriate way for me because i have many traffic flows and each flow has 1 packets, so it is very very difficult to count colllisions. I would be greatly thankful to you if you provide other solution. waiting to get urgent reply. thank you.
