In VANETs or Vehicular ad hoc Networks, vehicles represent the nodes, which communicate wirelessly. Every node sends the beacons (data packets) to update its position using GPSR protocol. The packets are forwarded through the best-effort delivery technique called Geographic Forwarding. In this paper, APU or Adaptive Positioning Routing has been used to evaluate the distance-based and speed based beaconing schemes on the basis of variation in number of nodes and in transmission range using NS-2 simulator.
