Re: [ns] How to find vehicle route information
Ajmal, NS2 does not know map, it only moves a node from point A to point B in straight line in a given velocity. Assume Node 0 is positioned at (100,100), if it is moving in one direction is, $ns_ at 0.0 $node_(0) setdest 150.0 150.0 1.0 to move in the opposite direction is, $ns_ at 0.0 $node_(0) setdest 50.0 50.0 1.0 Do note it has no negative value as the point of origin is (0,0) Good Luck. rgds Saravanan K On Wed, Aug 22, 2012 at 6:28 AM, ajmal khan engaj...@yahoo.com wrote: Dear all Hi I am working on VANET.

I have the Minimum Spanning Tree in NS2 and I want to use it in simulations of sensor networks(I'm using this algorithm to route data from the source to the sink). The problem is that I don't know where to start and how to do it. It would be really helpful of you people if you could post some links to resources from where I can get started on this.

Re: [ns] How to find vehicle route information
Dear Saravan Thanks a lot for your reply. I understand your point about movement of a node 0 in different direction. but i need to know about neighbors of node 0. if node 0 receives GPS information of neighbor nodes, how to know that they are moving in opposite direction, a neighbor node behind node 0 does not mean that he is moving in opposite direction just by looking at its position 50,50 as compared to node 0 position 100,100. I hope u understand my point, this is little difficult for me to know about the direction. If you are working in vanets,then u might have idea about different papers like VADD, Geoppos etc who are using direction of nighbors and also furtur route information of neighbor, which i have no idea how to figure out, thanks a lot once again for ur precious time. Hope i will find some helpful response soon.
