GPS free localization based on relative velocity in MANETs

A stable ranging localized network can be constructed by using the relative speed of the node pair, and the direction of motion of nodes. The network topology remains constant if the nodes move with same speed and in same direction. The direction of the NCS (Network Co ordinate System) by using proposed system is consistent when compared to [1]. The LRG (Local Reference Group) selection depends on the relative speed of the nodes.
