[ns] simulation of packet loss in wireless sensor network

[Muhammad Umar]

Hi ns-users,
 I am working on a robust routing protocol for WSNs. For that I have to 
simulate packet losses in the network. I want to drop the packets in the 
network according to some probability function e.g 5% of the reports sent to 
the sink should get dropped on their way to the sink. How can I implement 
this ????
Secondly can the wirelessphysical interface help in this regard, e.g Can I 
manipulate the value of the RXthreshold parameter inorder to attain the 
desired packet loss ( i-e The wireless interface should drop the packet if 
the received signal strength is less than a required minimum).
 Regards,
umer.
