In mobile ad hoc networks, each node is needed to maintain its location information with the neighbor nodes. For this purpose they transmit the beacon packet periodically, which is not fair in terms of update cost and performances in term of routing decision. To overcome this, the authors introduce the efficient beacon scheme based on mobility of node which uses two principles. 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.
