Thanks for your help If the number of nodes increased more numbers of packets are discarded. Actually I want to solve hidden terminal problem. Is there any built in procedure to solve it in TOSSIM.
If not how do I solve hidden teminal problem. I am using RTS and CTS packet to solve it. But I can't understand how to proceed. I have another doubt, I have 4 nodes in the sequence 1 -> 2 -> 3 -> 4. When node 1 sends packet to node 2, some packets can not received by node 2 because at the same time node 2 is sending packet to node 3. I think sending slot of node 2 is collide with sending slot of node 3. I don't know whether I am right or not. Why is it happening and how do I solve it.
