A Study on Adaptive Position Update for Geographic Routing in Manets

In geographic routing, nodes need to maintain up-to-date positions of their immediate neighbors for making effective forwarding decisions. Periodic broadcasting of beacon packets that contain the geographic location of the nodes is a popular method used by most geographic routing protocols to maintain neighbor positions. A node transmits its next beacon if the deviation in its predicted value with its actual location is more than the acceptable error range. When a node overhears a data packet transmission it transmit beacon as a response to it.
