NS users, I want to simulate IEEE 802.11b WLAN and see the plot between throughput vs number of stations. I need a topology like this: The mobile stations are randomly distributed in a circle with a radius of 100 meters and the access point is located in the center of the circle.The network is under a heavy load condition and traffic is evenly distributed across all the nodes in the network. Packets arrive the network according to the poisson distribution and simulation stops after 1 million packets. Can anyone please suggest me how to write tcl code for this. Please send me the tcl code or a part of tcl code for the above scenario. please help me. I need it urgently. Thanks in advance.
