AN ENHANCED APU TECHNIQUE BASED GEOGRAPHIC ROUTING IN MANET USING DESTINATION AWARE ROUTING PROTOCOL

Mobile Ad - hoc Network (MANET) is a set of wireless mobile nodes. These networks are decentralised system. Here nodes communicate with each other without any centralized access points or base stations. In this type of network, each node acts both as a router and as a host at the same time. Routing in MANET is to find the effic ient path to transfer the data from source to destination. APU strategy is routing strategy for geographic routing in Mobile ad - hoc network which dynamically adjust the frequency of position updates based on the mobility dynamics of the nodes and the forwa rding patterns in the network. The beacon updates include the current location and velocity of the nodes. An Enhanced APU strategy in the proposed system use destination aware routing with minimum distance dynamically adjusts the beacon update intervals ba sed on the minimum distance from source to destination, mobility dynamics of the nodes and the forwarding patterns in the network. Results of the proposed system are compared with Periodic Beaconing on the basis of packet delivery ratio, beacon overhead, e nergy consumption. Experiment results show a high improvement in results on the parameters discussed.
