What I want to know is how can I calculate the coverage radius of each node or how can I change the default value to something around 50-100m, what parameters do I need to change and what formula and propagation model does ns2 uses to calculate that. I have moved the values of gamma from 2.0 to 5.0 and I have noticed that the coverage radius has decrease but I want to be able to know the exact distance. Also the value of Pt inside that tcl is given en mW?
