Re: [ns] How to find vehicle route information
Dear Ajmal I'm working on VANET too, and I use SUMO as mobility generator that its output is something similar to VanetMobiSim . Recognizing road map information by NS2 is also my problem that couldn't solve yet. But about vehicle's direction, you can use their velocity vector information that are available in NS2 for mobile nodes. Easily you can find angle or direction ( or actually Cosine(angle) ) between two vectors by applying dot product formula. If it's possible, please inform me whenever you find any information about using road map information in NS2.

I need to know how to find a route of a vehicle. I can generate mobility traces of vehicles in VanetMobisim and it looks like this. $ns_ at 0.0 $node_(0) setdest 714.9497484683059 494.9497484683058 0.75267607 i.e. node 0 will move towards mentioned (x,y) coordinates at speed of 0.752 but it does not give any information which route it will follow on a given map. Please help me how to figure out the routes of vehicles. If there is any other tool that can help. please mention that as well. Also i would like to know how to find that a vehicle is moving in opposite direction. your help will be greatly appreciated.

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.

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.
