[ns] good reply in DSR
hello well i want to know wht this code means in DSR code n how is it
checking/deciding wether its a good/bad reply on what basis...! i will
really be thankful for your help...!
bool good_reply = true;
//#ifdef USE_GOD_FEEDBACK
/* check to see if this reply is valid or not using god info */
int i;
for (i = 0; i reply_route.length()-1 ; i++)
if (God::instance()-hops(reply_route[i].getNSAddr_t(),
reply_route[i+1].getNSAddr_t()) != 1)
{
good_reply = false;
break;
}

Re: [ns] How to get the routing information from DSR
well u can print the information of the routes in route reply,,,! tht is easy n c how many routes are available n which route is being used ... length of route and nodes in the route replies,..! and wat is ur work on DSR?? RJ Lin wrote: Hi, Mubashir, Thanks for your reply. I have see the FAQs by Bryan. but there is not detail description. I still dont know hoe to get this information. For example, when a packet is sending from a source, the routing is existed. How to get that routing and print it? Is it ablt to get from DSR header? or I have to search it from Cache?

[ns] IEEE802.11 PSM's source codes!
Hi all users, Do somebody have IEEE802.11 PSM's (The power save mode MAC protocol) source codes? OR Do you know where can I find them? I really need them! If you have, please send me too! Thanks, -- Elham Noori

Re: [ns] Network Coding in NS2
Hi Is anyone working on network coding simulation in NS2. Is there any patch available? Thanks Amit Khanna
[ns] Bandwidth/utilization graph Ns2
Hello, I am research/Msc student at the King's College London. I am building a wired topology.I need to create some graphs to see the congestion/utilization, the tcp flow for instance. How could I do that in NS2 ? What script should I add to my code to make it possible ? Thanks you very much for helping me out. Alexandre Jaron, KCL MSc student.
Re: [ns] Performance of AOMDV
HI Mr Charley Cheng, Hi everyone I’m a student who have the some probleme and I need to value the facts of multipath routing in mobile ad hoc networks in terms of Packet Loss compared to AODV protocol. I works in ns2.34 . the results found for AOMDV are always worse than AODV protocol. Can you help me in this context? Thank you very much. Héni. Charley Cheng wrote: Hi everyone, I am trying to reproduce the simulations results of AOMDV paper. I followed the same parameters described in the paper, which are listed below: 1. Network size: 1000m*1000m 2. Number of nodes: 100 nodes 3. Radio transmission range: 250m 4. Channel bit rate: 2Mb/s 5. 50 CBR/UDP connections; each connection strats at a random time during the intial 100s of the simulation and stay till the end 6. Packet size: 512 bytes 7. Packet rate: 1 packets/s 8. Simulation time: 1000s with the inital 250s taken as the warmup period Moreover, according to AOMDV paper, I also disabled expanding ring search and local repair, and enabled periodic hello messages for neighborhood information maintenance by disabling link layer detection. Based on the above parameters, I ran simulations for AODV in varying node speed (from 1 m/s to 30 m/s). I got the packet loss from 6.14% to 54%. However, the latency (or end-to-end delay) is very low (below 0.11s). It is not reasonable. So, could anyone tell me what are the problems I encountered? Thanks in advance.

Re: [ns] Performance of AOMDV
Thank you very much Mr Charley for your response :-) I simulated the AOMDV protocol under NS 2.34 using the following parameters: 1. Network size: 1500m*500m 2. Number of nodes: 50 nodes 3. Radio transmission range: 250m 4. Channel bit rate: 2Mb/s 5. 10 CBR/UDP connections; each connection strats at a random time during the intial 50s of the simulation and stay till the end 6. Packet size: 512 bytes 7. Packet rate: 5 packets/s 8. Simulation time: 2000s with the inital 200 s taken as the warmup period 9. Modele de mobilité: RWM 10. Pause time: 10s Best regards.

[ns] How can I get the wireless nodes' position information in C++ code.
hello everyone. I want to improve DSR routing protocol .I want to define a node's interface by the distances from other nodes. How can I tell what node code is currently executing on .And how can I get the position informantion of all other nodes in the node's C++ code? yours zhang8677
