[ns] implementing a new protocol

Hi All, I'm getting confused while implementing a new protocol. I'm making changes in c++ code of AODV protocol, but don't know how the control flows, meaning by, there is no main() function in the c++ program. So, can anyone tell me how the complete opearation of a protocol is controlled. If

Re: [ns] TCP and packet drop: where are the retransmitted packets?

Well, I assume that cong_action is Congestion Action, and dropped packets are mainly caused by congestion, which leads to retransmission. So this makes sense. Thanks Amit! - Arne _ Fra: Amit Mondal [mailto:[EMAIL PROTECTED] Sendt: 28. juni 2006 00:13 Til: Arne Lie Emne: Re: [ns] TCP

[ns] Wireless Simulation questions

I am getting myself familiar with ns v2.29 and I have some questions on wireless simulations. I see that there are parameters defining Antenna type, propagation model, physics, routing protocol, MAC type etc. Where is the channel bandwidth defined and the range of communication for the mobile

Hello Varrian, Thanks for the code. Which is the main udp you are referring to? How will packets be copied from the sink to the source (assuming i have a single source/sink agent) and then retransmitted to n2? Thank you. On 6/27/06, Varrian Hall [EMAIL PROTECTED] wrote: Hi, I think

This sounds like you haven't installed nam properly. Make sure you have added the path to the nam binary to your shell variable $PATH (I am presuming you are using Linux and bash as you didn't specify) using the following : export $PATH=$PATH:/path/to/nam/binary Note : this will have to be

Re: [ns] How can I add extension to packets in AODV?

you can change AODV packet header (RREQUEST,RREPLY,RERROR) with yours. Or you can add some extra fields in this packet headers. All the headers using by the AODV are defined in the aodv_packet.h file. For example in the following code, temp field is added by me. Guzin ULUTAS (CEng) struct
