Hi Dheepa, One way of reducing the signal range is to set an appropriate value of the receiving threshold in the network interface (in your tcl script), i.e
Phy/WirelessPhy set RXThresh_ <value> A separate C program is provided at ~ns/indep-utils/propagation/threshold.cc to compute the receiving threshold. You have to compiled it, then you can use the executable to compute the threshold as follows: threshold -m <propagation-model> [other-options] distance Ex: threshold -m Shadowing -r 0.95 50. Here the propagation model is Shadowing, the communication range is set to 50m, and 0.95 is the rate of correctly received packets. More details can be found in ns_manual. Hope this helps. Bye.
