[ns] Does DSDV stores the Routing table of its neighbours?????
Hi Jeevesh, DSDV stores the Routing table for each node that is modified by the information received by the node's neighbor nodes. rtable.h file contains class RoutingTable and rtable.cc stores each entry, contains information about the current node's neighbors, into rtable_ent *rtab member variable of RoutingTable class. In dsdv.cc, makeupdate function builds a packet which contains information about the current node's neighbors. if updatetype=1, all of the records hold by the rtab member will be send, else appropriate records will be send. I hope, this answer helps you. Guzin ULUTAS (Computer Engineer)
Re: [ns] Does DSDV stores the Routing table of its neighbours?????
Hi Jeevesh, Actually DSDV doesn't have the all the neighbours's routing table with it, at the time of calculation of shortest path. it has got only necessary information gathered by the neighbor nodes during triggered and periodic update. It gets the routing update packet from its neighbors, and compare this packet with its routing table. Necessary updates will be implemented. But not all the table stored by this node.

Re: [ns] FW: Re: nam: permission denied
thanks tathagata and all who answered effectively I added the path of that directories, but in the wrong form (e.g., path=c:\cygwin\ns-allinone-2.29 instead of path=/ns-allinone-2.29 and similar) now the more difficult task: understand ns ;-) sergio From: tathagata dasgupta [EMAIL PROTECTED] To: Sergio Torassa [EMAIL PROTECTED] Subject: Re: [ns] FW: Re: nam: permission denied Date: Fri, 14 Apr 2006 04:01:54 +0530 You need to add(PATH=$PATH:/..) the absolute paths of the directories that house the binaries for nam and ns to your path variable. for example My PATH variable looks like this /usr/local/bin:/usr/local/sbin:/sbin:/usr/sbin:/bin:/usr/bin:/usr/bin/X11:/usr/games:/bin/:/usr/sbin:/opt/jdk1.5.0_06/bin:/usr/local/ns-2/ns- 2.29:/usr/local/ns-2 I had the same problem like yours and chaging it took care Hope this helps
[ns] number of paquets receive and send don't change with mobility
Hello everybody that makes one week i have this probleme and it doesn't advance i want to plot the curve nombre of paquets received / nombre of paquets send in fuction to the mobility, so i do it this stages: 1) i generated a scenario with ./setdest -n 50 -p 5 -m 0 - M x -t 200 -x 500 -y 500 fx x:nombre between 10 and 100 2)i simulate the tcl file with 10 scenarios 3)i remarque that the number of paquets received and the number of paquets send don't change ,what do you think about that its logical?! i alreday give you my file tcl;and you tell me thats probably due to the model propagation i use it,ok i change the madel,i use random-waypoint model,but i have the same results, i ma bloqued,if you have any ideas,and you have a time,help me please THank you - Faites de Yahoo! votre page d'accueil sur le web pour retrouver directement vos services préférés : vérifiez vos nouveaux mails, lancez vos recherches et suivez l'actualité en temps réel.

[ns] Help needed for HCCA patch on NS-2.27
Hi! I downloaded and installed the HCCA patch for NS-2.27 from http://info.iet.unipi.it/~cng/ns2hcca/ However, I am not able to find out how the stations get the access to the channel. Consider the offline TXOP list that is created. Suppose it contains the TXOP times for the stations 1,2,5,6. How does the patch ensure that first only station 1 will access the channel, and then stations 2, 5, 6 ... and so on. If anybody can throw some light on this issue, I'll be really grateful.

Re: [ns] help with understanding AODV
Vinod, Kapil, Kanthi, Thank you for your replies. I think the timer refresh is not sufficient enough in my case and the route (re-)requests are happening not so frequently i.e. it is not in sync w/ the mobility (i am not yet sure how that can be handled). Due to this, there is packet loss and the delivery ratio is low. I will look further into aodv implementation to see how the fine-tuning of timers is done to handle node mobility. Regards, Sita hi sita, afaik...there are route refresh timers in aodv. so whenever a route table entry expires , the source broadcasts route requests (ofcourse only if it has to send more data pkts) once again and the route to the destination is recomputed. the timers are fine-tuned to according to the mobility. hope this helps, vinod -- Vinod Kone, Btech,Computer Science, VIII sem, Room 177,Kapili, IIT Guwahati.

Re: [ns] Running nam on cygwin
Hello Tuhin Kanti Sharma, You are probably trying to use NS on a linux server with ssh. Am I wrong? Anyway, typing the following commands in your console should help you a lot: export DISPLAY = localhost:0 and if you are using ssh, please use the option -Y after having set the DISPLAY variable with the previous command, for example:: ssh -Y -l mydistantlogin mydistantcomputername Mit freundlichen Grüßen, with kind regards, cordialement, -- Gilles BERTRAND Institut National des Télécommunications (GET)- Universität Stuttgart http://raimizou.com/GB_online/pages/network_simulator.php -- Tuhin Kanti Sharma a écrit : hi, I m getting this error: $ nam MySnoop.nam nam: no display name and no $DISPLAY environment variable when I try to run nam on cygwin.if ne1 can hlp I would be obliged.
