Hi, Could anybody please suggest whether there is any provision of fragmentation and reassembling of packet in LL or MAC or PHY in NS2? Regards, Nill
[ns] problem in simulating a wired cum wireless link between two nodes...
Hi Alysson,
Thanks for your time and effort.
However, I would highly appreciate if you could suggest me something to
transfer data between BS or how can I simulate a same kind of topology. My
ultimate aim is to simulate a wireless link between two nodes where the
other side of both the nodes is a wired interface...
Thanking you in anticipation...
Regards,
Samar

Hi
You had made some hierarquical mistake.
But dont transfer data between BS yet.
I'll see it latter...
See you...

Hi Alysson Oliveria,
Thanks for your response...
I am attaching herewith my scenario.tcl ... I wanted just to make a
wireless link between two nodes while another interface of the node is a
wired link. I am not sure where I am mistaken...
Thanking you for your timely help
Regards,
Sam

Hi Sam Sha,
Would you send you tcl code? May be you had any topology mistake!
Please, see:

Hi all,
I want to simulate a wireless link between two nodes. where both the
nodes
have a wired interface as well. So my simulation topology is like - I
receive the data from the wired link on node-1, I transmit the same on
the
wireless link to node-2, now node-2 receives the data and sends on the
wired
interface to other nodes in the network.
I tried making the two nodes as the base station nodes I get the
following
error :
num_nodes is set 2
INITIALIZE THE LIST xListHead
--- Classfier::no-slot{} default handler (tcl/lib/ns-lib.tcl) ---

content dump:

Please provide any suggestion or any documentation that will help me in
simulating the scenario
Thank you all in anticipation...
Regards,
Sam

Try defining the process this way:
proc discover_ferry { src dst now index } {
global ns_ node_
...
...
...
}
Hope it helps!

[ns] Trace Analyzer
Hello everybody, I'm making some simulations, and i 'll need to analyze. So I have been searching trace analyzers, and I wanted to know if you could recommend some trace analyzer that calculates the total average delay. I hope you can help me. thank you!
