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.

Please help me

Thanks
