[ns] the distance between nodes in adhoc network using olsr routing protocole
Hello everybody i wish you will help me ,its very urgent thanks in advance. i want to calculate the distance between nodes ;by using the delay of paquets HELLO;i use the olsr routing protocole i wana to know if it true: delay= time of reception to the HELLO- time of sending the HELLO distance between nodes=(3,6 *10^8) *delay because i want to use the distance betwwen nodes;i have two ideas: 1)use the distance between nodes i have already give the relation with delay 2)use the GPS positioning system,for giving the x,y,z for the nodes thanks,i am waiting for your ansswer faithfully yours;and best regards Remarque:i have already tryed in ns2 to test if it is true that delay= time of reception to the HELLO- time of sending the HELLO distance between nodes=(3,6 *10^8) *delay i found that it is not true,i find distance betwen nodes/delay=47 and not 3*10^8 please i am waiting for your help;help me - 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] in the trace file the lines are just a messages udp or cbr
hello thank you for your reponse,i would like to ask you a question,the trace file its contain juste the cbr or tcp messages,or this contain the HELLO and TC messages also. because i remarque that the nombre of paquets receive is more than the number of paquets send and i think its not logical. other think;i would like to know if adressing its very importante,and for having an ideas of the nombre of paquets receive by a node,i must to count de number of adress apears in trace file,and not the number of node apears ,because the node can be juste a router of message,and not the real destinantion Thank you for your help;thanks - 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.

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] the nombre of paquets don't change despite of the mobility
Hello everybody
I have a problem that makes some days I am blocks.
I achieved several scripts of mobility in order to draw the curve: number of
packets received / number of packets gave out according to the mobility.
I generated several scripts with. / setdest,with variable M between 10 and 100.
I notice that the number of packets received / number of packets didn't give
out changes
I give you my script tcl
s1:file of scenario
f1:file of trafic exchange
and we use 10 scenario (M=10,M=20.M=100)
Please help
