In MANET, each node is needed to maintain its location information with the neighbor nodes for geographic routing. For this purpose they transmit the beacon packet periodically, which is not efficient in geographic routing due to packet collision. Also it has its effects in terms of update cost. Further the inaccuracy in local topology has its impact on the performance geographic routing. To overcome this in this paper we introduce the prediction scheme for Beacon Update and a prediction Scheme

For geographic routing we use Greedy Perimeter Stateless Routing (GRPS) Protocol with greedy techniques, which select its next hop based on the optimization criteria. When greedy fails in selecting the next node nearest to destination we use perimeter rule which search over the perimeter of the node for destination node. Using the Mobility prediction scheme for Beacon technique in GPSR we try to decrease the update cost and increase accuracy of local topology.
