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.
