Position Update in Mobile Ad-hoc Network

The Ad-hoc networks come to be very widespread. Everybody is using these networks because the decentralized nature of wireless ad hoc networks.Wireless ad hoc networks makes them suitable for a variety of applications where central nodes can't be relied on and may improve the scalability of networks compared to wireless managed networks. Though theoretical and practical limits to the overall capacity of such networks have been identified. In geographic routing, nodes need to maintain up-to-date positions of their immediate neighbors for making effective forwarding decisions. We contend and demonstrate that periodic beaconing regardless of the node mobility and traffic patterns in the network is not attractive from both update cost and routing performance points of view. In this, we propose the Adaptive Location Update strategy for geographic routing. Which dynamically adjusts the frequency of position updates based on the mobility dynamics of the nodes and the forwarding patterns in the network. And resolve the Unknown node problem when it exist to increase the efficiency of this method by introducing the phenomenon of selecting node from existing ones or unknown node.
