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. Be successful Mojtaba ________________________________ From: ajmal khan <engaj...@yahoo.com> To: "ns-users@isi.edu" <ns-users@ISI.EDU> Sent: Wednesday, August 22, 2012 1:28 PM Subject: [ns] How to find vehicle route information Dear all Hi I am working on VANET. 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.
