[ns] help me in finding the problem
Hi! I am simulating the WSN using energy model but I have the follwoing confusions 1. As you can see that I have defined the grid 100m *100 m, and specifically defined the node positions 10 m a part from each other along x-axis. But when i start simulaion the nodes initially are invisible for some time then they appeared in overlapped fashion... why? I have defined the thredhold but It didn't work as when in simualtion environment I manually drag the sink and source wide a part they still exchange messages directly... how can I overcome this?

Re: [ns] help me regarding the make file plzzzzzz
Hello Tamer, I think there are two ns-2 groups, the releases earlier thank 2.30 and later thank and including 2.30. The first group requires older c++ compiler and you should only install them in a linux fedora version earlier than core 5. This applies to your 2.29, which should be installed either in core 4 or earlier. The latter should be installed int a core 5 or later release of Fedora.
