[ns] Urgent Help Needed with running AODV on NS-2.34

[Anoop thesis]

Hi Fellow ns2 users,

 I am pretty new to NS2 and need to learn it for my Thesis.

I am trying to simulate AODV in ns2.34. It worked fine for a 3 node example
where I could simply give the node positions and work it out.

However, i am now trying to modify the 50 node example ( wireless.tcl) for a
AODV scenario.

The following are the changes I have implemented in the 3-node example. I
may have made some basic mistakes. But please help me out.

I have already created the scenario using the cmu generator setdest and
cbrgen.


Modified Example for 50 node AODV:

# Define options

set val(prop)           Propagation/TwoRayGround   ;# radio-propagation

set val(ant)            Antenna/OmniAntenna        ;# antenna model
set val(ifqlen)         50                         ;# max packet in ifq
set val(nn)             50                          ;# number of mobilenodes
