Further to my previous email. I have made following changes in ns-lib.tcl to

switch -exact $routingAgent_ {

}
default {
puts "Wrong node routing agent:$routingAgent_"

}
after remake, I again receive following message:
num_nodes is set 50
Wrong node routing agent!
It should have given following error:
Wrong node routing agent: MPDSR
This mean that after remake, changes have not been incorporated in ns-lib.tcl.

You need to check the routing protocol you are using
in your tcl script. If you have written the code of
smr afresh, you need to make changes at several places
like
config, routing agent, etc. Check whether you have
made all those updates.
Hope this helps,

Re: [ns] SWAN implementation

So plz if any one have the SWAN implementation on ns2, I will be very grateful if you send it to me!!! thanks for any help!
[ns] Scenario File
Hello How I can set scenario file with random velocities for the following parameters: traffic type: cbr total nodes: 50 source nodes: 20 seed 1.0 rate 10 packets/sec dimensions: 1000m x 1000m pause time: 30 sec random velocity: 0-20m/s simulation time: 800s Cheers Haseeb

[ns] Connection Pattern
Hi I want to set a connection pattern using cbrgen with following parameters: traffic type: cbr total nodes: 50 source nodes: 30 seed 1.0 rate 10 packets/sec Am I doing the right way or please rectify. "ns cbrgen.tcl -type cbr -nn 50 -seed 1.0 -mc 30 -rate 10.0" Cheers Haseeb
[ns] Scenario Files
Hi 1. I want to set constant speeds of 0, 1, 5, 10 and 20 m/s for set of experiments that varies the velocity for 20 sources of 50 nodes network. The packet sending rate is fixed at 10 packets / sec. I am setting the scenario file for speed of 1 m/s as ./setdest -v 1 -n 50 -p 30.0 -M 1.0 -t 800 -x 1000 -y 1000. Please confirm. 2. How I can set random velocity of 0-20 m/s for 50 nodes. The network load is varied by changing the number of sources. The packet sending rate is still fixed at 10 packets / second. The number of sources is varied from 10 to 50 in intervals of 10. Cheers Haseeb
[ns] packet rate in cbrgen
Hi To create CBR connecions, run ns cbrgen.tcl [-type cbr|tcp] [-nn nodes] [-seed seed] [-mc connections] [-rate rate] For example , ns cbrgen.tcl -type cbr -nn 50 -seed 1.0 -mc 20 -rate ? If I want to set rate at 10 packets/sec, what should I mention in rate 10 or 1/10 as rate=1/interval. README file for cbrgen as well as connection pattern files (/mobility/scene...)seem confusing. Please clarify. Cheers Haseeb
[ns] SWAN Implementation
Please help me in answering following qiuestions regarding implementation of
SWAN code in ns2.1b9a:
1. I didnt get following files from SWANs website:

set opt(sc) "../Scene/S1/mobility.tcl"
2. When I run, I get the following error:

[ns] normalized routing load, normalized mac load and average hop count
Anyone who know the formula to calculate normalized routing load, normalized mac load and average hop count. Cheers Haseeb
[ns] How to calculate Normalized Routing Load?
Hi
I have written the perl script to calculate the
normalized routing load but my results are very
strange.Can anybody tell me is it right formula for my
calculation which is given below?
Note: i am using old format of tracing
1. I am getting the receives like: if the flags are
"r" and "AGT" and "cbr" then recieves++.
2.I am getting routing packets like: if the flags are
("s" or "f") and "RTR" and ( "aodv" or "dsr" or
"message") then routing++;
3. And i am getting nrload=routing/receives
--------
Please help me to clear this doubt
Thank you in advance ...
