Re: [ns] collisions in 802.11 or interference

Hello Imad The 802.11 Standard uses CSMA/CA ( Carrier Sense Multiple Access with Collision Avoidance ). It does not use collision detection. And 802.11.ccshould be coded according to the standard, so I guess you won't be able to capture the collided packets inside 802.11.cc. I think you can only

If i develop the switched ethernet simulation than in which tcl scenario file should i use to test whether my code is working or not. Haider s.korea

[ns] Correct use of mac 802.11 in MANET network

Hello to everybody! I would know your opinion about my solution. I'm working in MANET routing context and I'm simulating a simple network made up by 4 fixed wireless nodes (A,B,C,D) with mac layer 802_11 (dataRate_ set to 11Mb) and a mobile node (E) with mac layer 802_11 but dataRate_ set to

[ns] Large network simulation problem

Hi all! I've got a problem simulating a network with 1000 nodes. I've a tcl script that simulate a network with many nodes moving all around. When I analyze the trace file with up to 100 nodes, the results look correct, but with 500 or 1000 nodes I can't get correct results. For example that's

Re: [ns] Large network simulation problem

Can you post here your tcl script, that way you could analyse better the results! Luís Barreto On Sat, Nov 15, 2008 at 11:01 AM, coorasse [EMAIL PROTECTED] wrote: Hi all! I've got a problem simulating a network with 1000 nodes. I've a tcl script that simulate a network with many nodes

Re: [ns] Large network simulation problem

That's my tcl simulation script. It's a base script without the mobility model that's it is put where you read #INITIALPOSITION. http://www.nabble.com/file/p20514864/prova1.tcl prova1.tcl I change the number of nodes and the topology dimensions from that script when I wanna do a different

[ns] I think it is AODV bug for interface queue dismatch

Hi all Recently, I face segmentation fault with AODV. So I check all the AODV C/C++ object and tcl. I found that In AODV, there's ifq which is PriQueue. In that case, when writing a wirelss network TCL file, declare set opt(ifq) Queue/DRR or set opt(ifq) Queue/RED, there's a chance will
