How to set the transmitting power of wireless nodes in ns2
Hi Everyone,
I am new to ns2, i am using ubuntu 12.04 lts and ns-2.33
1.i need to know how to set and increase the transmitting power of wireless nodes in ns2,
2.how to set the distance covered by wireless node
If anyone knows thwn kindly tell me....
i used follwing code, but i am not getting output , i am getting the nam window in output but there is no communnication (packet transmission) exists between nodes even i attached TCP traffic to source and sink
Code:
