Re: [ns] MAC layer implementation
Dear Gomathi, Your question is not clear. What neighbor you are looking for? If you are looking for routing neighbours you can only do in routing layer. If you are looking for Radio Range or Carrier Sense neightbour you can do either using a) routing.cc - this approach has been recently elaborated, kindly check the NS2 messages archive ,or b) channel.cc - WirelessChannel::getAffectedNodes() would be of your interest. Do take note, if you use this approach, you would need to modify the square radio range to a circular radio range to better exhibit the transmission property of radio of a wireless node. Dont think you could do MAC layer in the present form, as the neighbour management is only done in routing layer. Good Luck. rgds Saravanan K On Mon, May 27, 2013 at 4:13 AM, Gomathi Rajamanickam gomathi250...@gmail.com wrote: Hi, I am doing my project in MAC layer.

Re: [ns] Queue Delay
Hi, Tried to read on queue monitor in NS2 manual or internet. Some of the below can be solved by using it.

Is there any way in NS2 to know the number of packets present in the queue of a particular node. And also how to calculate what is the time taken to empty the queue if it is full. Please let me know if any one has any idea about the above two. Thanks -- Bhyravajosyula Sai Vishnu Kiran MS in Computer Science mail-id: sbhyr...@asu.edu
[ns] help-to create a table for maintaining neighbor list
Sir, I am an M.tech student. Your posts are very much helpful for a beginner like me in NS2. As a part of my project,I have to maintain all the neighbor nodes of all nodes in the network. Since I have to maintain neighbor node corresponding to each node, I gave a two dimensional array for that. I am working in AODV protocol. Whenever the insert function of recvHello() is called my function add() will also be called. But it is showing errors. Sir, is it possible to give two dimensional arrays with type nsaddr_t in NS2? Could you please help me to solve this problem? Thanks for your valuable time. Regards, Sony
