[ns] [MANET] Lucent WaveLAN vs. 802.11 !?
Hello, I have a few questions concerning IEEE 802.11 simulation using NS : First, the 914 Mhz Lucent WaveLAN DSSS radio interface exists in NS. All the examples simulating this technology use the Mac/802_11 Class, but IEEE 802.11 is not implemented in the 914MHz Lucent WaveLAN. Is this a problem ? If I intend to simulate the IEEE 802.11 Lucent WaveLAN, what should I define (new Classes or simply change the values of CPThresh_, CSThresh_, RXThresh_, Rb_ , Pt_ , freq_ , L_ what should the new values be ?) Why is NS not fully appropriate to simulate the real behavior of a 802.11 network ? Probably because of the propagation model itself, but is it the only reason ? Best regards Alex
[ns] [MANET] RANDOM motion, connection CBR sources - Each simulation
Hi everybuddy, I want to have a fully random scenarion in square area of 50 mobile nodes... But every simulation yields the same output .. Each time I simulate, how can I have: a.. different random CBR source each time b.. different connection c.. different mobility pattern a.. also random speed (0-20 m/s) too d.. pause time = 0 sec (I mean) Thanx in advance Alex
[ns] MANET Any DoS ATTACK to Routing
Hi everyone, Due to versatile kinds of simulations and research on security and Intrusion detection, the source code of the attacks written on NS-2 (modified C++ code) must be so AVAILABLE and routine... I will highly appreciate you if you can send me the files of malicious agents (DSRagent.cc and ...) that perform these DoS attacks of routing: a.. Black Hole (Especialy) [I'VE FOCUSED] b.. Gray Hole c.. FFRR (False Frequent Routing Request) d.. JellyFish e.. etc. Thanks in advance Cheers, Alex Nixad
Re: [ns] MANET Error! just by changing AODV to DSR!
Thank you Virginia ... I did this modification, and the simulation has started successfully, and simulating finished after more than 1 hour ... My simulation time is just 900 sec! I don't know what is wrong with CMU model ... Why does it long too much?! Also TRACE file became so large!!! ... Before with AODV was about 1.37MB, NOW it's become 9.8MB! king regards, Alex Nixad. - Original Message - From: Virginia Thoma [EMAIL PROTECTED] To: 'S.

Hi, You need change this parameter: set opt(ifq) Queue/DropTail/PriQueue. Change to set opt(ifq) CMUPriQueue Virginia. -Mensagem original- De: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Em nome de S.

Hi everyone, I'm simulating a ad hoc network with 50 random mobile nodes ... and 15 random CBR traffic ... The simulation is successful under AODV protocol; but when I just define DSR routing protocol for same network, it FAILS with following ERROR: Segmentation fault core dumped Kind regards, Alex Nixad
[ns] MANET Modified DSR meanwhile DSR
Hi everyone, In my simulation, 50 random mobile nodes are working under DSR routing protocol ... By a reason, few RANDOM nodes have to treat a MODIFED DSR (so I've editted DSRagent.cc as DSR_2.cc in DSR2 folder) I wanna implement these different routing protocols SIMULTANEOUSLY in my testbed : DSR beside modified DSR How can I FLAG in TCL file that one or few node uses MODIFIED dsragent.cc (DSR_2.cc) and rest use the NORMAL dsragent.cc? Regards, Alex Nixad.
[ns] ! NS2 - Forum Suggestion (GENERAL!)
Dear all, Is there any FORUM for NS-2? This routine of EMAIL sending and receiving is not perfect ... bad performance: 1.Many of questions are so frequent (e.g. which version of NS2 on which release of Linux...) Even some questions have asked long ago, then NOW REPEATED QUERY WITHOUT ANSWER ... 2.'Coz in the Mail Archive, finding the related answer regards to their SUBJECT is TIME-CONSUMING With FORUM, all of unnecessary traffic and time to send repeated query will be eliminate. Regards, S. Alex Nixad
