Friends!!

Suggest me best hierarchical routing protocol for WSN which is fault
tolerant.

[ns] Help from people working on WSN in NS2

[Munivenkatesh K]

Hello All,

I need a sample program for WSN in NS2. Can any one tell me the default
transmission range of a sensor node and how to put a node in sleep mode and
again to wake up the node.

Thanks  Regards,

Dear all,

if any one has directional antenna sample scripts pl send me. And kindly
tell me the execution process also if it is different from normal one.

try the following modified code of u r program...it will work. b4 that you
just verfiy whether u have set environment varible in .bashrc or not. all
the beast.
