[ns] packet delivery ratio in aodv?

[klpang]

hi all,

I'm running aodv with communication range equal to 80m. To achieve this, i changed the 
Phy/WirelessPhy set RXThresh_ 3.00435e-08 using the propagation model provided in ns2, threshold.cc. 

My question is, is there any other parameters that i need to set? please advise.

I suspect something is missing, because for my simulation of 100 nodes, static, with 8 packets/sec the packet delivery ratio is only 0.1868, which is very low. Any clue what's wrong? 

Thank you very much

regards
