I am using NS-2 for creating a mobile node . actually those nodes are Wireless Sensor Nodes created by mannasim.
My scenario as the following:
a mobile node will move between 4 places and wait for some time
and it issues 4 move commandes like
set_destination(new_x,new_y,SPEED);
set_destination(new_x1,new_y1,SPEED);
set_destination(new_x2,new_y2,SPEED);
set_destination(new_x3,new_y3,SPEED);
from C++ code. this pices of code allow a node to move from its current location to new_x and new_y location at speed of SPEED value
However
just when the last command was executed, it didn't allow the previous ones to finish.
So the mobile node will got to new_x3 and new_y3.
So my question is how we can wait until reaching the first place before moving to the next one? In othe words, how we can know that the mobile node has reached one desination and the event was successfully finished?
Thanks
You can enable the mobility in ns-2 by using example command like this
syntax is
object at time "node number setdest x position y position speed"
$ns_ at 2.0 "$node_(4) setdest 300.0 400.0 50.0"
same for mobility you need to set....
Can anybody tell me about the specific parameters that must be considered in case 802.11 is used to Network Mobile Robots designed to mitigatet disasters like Fire in a large residential buildings.
it depends on the situatation and what you want to do. For example, 802.11 can solve hidden problem and provide a way for accessing AP through PCF and DCF.
However, NS-2 couldn't simulate your robot. you may use webots.
I want to modify OLSR and test its performance in environments where connectivity loss is major potential issue. I am of the opinion that parameter like signal strength should have some weight in calculating the routing tables. Please suggest which simulatore allows to modify the route calculation algorithm in OLSR. At phy i want to use 802.11 in adhoc mode. May be I am a bit confused in my concepts. Would be great if you can clear my mind on this.
Hi,
i want record no. Of times node moves during the simulation run and also during particular duration. Can anyone guide how to do this? My tcl script is using mobility pattern file generated by mobility generating tool.
Regards,

is it possible to have random movement of nodes? Consider 50 nodes in a 1000*1000 meter environment.
Thanks for all you. The problem was solved by acteating a timer after each step
Did you use the amount the speed of your node in your c++ code too? If yes, how could you did it?
Salam ,Comment être un code pour les simulations suivant:
deux noeuds N0 et N1. Le noeud N0 envoie au noeud N1un flux CBR. Le trafic commence à 1s et s’achève à 250s. Le temps de simulation étant 300s et le protocole de routage étant AODV. Le noeud N1est fixe, alors que le noeud N1 se déplace vers la droite avec une vitesse égale à 1m/s . La distance initiale entre les deux noeuds vaut 50 mètres et la La distance final 200 métres !!!
