[ns] AODV tcl script

2013-05-15 Thread Himanshu Bisht 

Hi

can anyone provide me the tcl script for simulating a network having
at-least 50 nodes that moves in a random way. I want to simulate the
Aodv protocol and check for its pdr, throughput and energy
consumption.

[ns] help my friends

please my fiends,
How could i read a field from each packet as they passes through each node in 
the simulation,
where could i add a function to do this

please help

Hi, the daemon request me to re-send my message, so I do so. (I have searched 
for FAQ and mailing list, and I still can't find a solution.)

Hi,
Can anyone tell me how should I fix this problem? I have a problem in attaching 
more than one applications to one agent.
There are two nodes(Source and Destination) in my environment and here are some 
features:1. I attached a loss-monitor agent on Destination node. 2. I attached 
an udp agent on Source node.3. I attached 9 applications on the udp agent by 
following declaration: set nExpGen 9 for {set i 1} {$i = $nExpGen} 
{incr i} { set eee($i) [new Application/Traffic/Exponential]
 $eee($i) attach-agent $udp $ns connect $eee($i) $lmt # 
nExpGen= number of exponential generators # eee = exponential application   
  # lmt = loss-monitor agent4. I got errors cant read agent address: no such 
variable.. when running my tcl file ( see [error message])5. Did I use the 
wrong way to attach these applications to the agent? How can I fix that?
ps. I am running ns-2.35 on Ubuntu 12.10Thank you all in advance.
Regards,Frank
