Enabling Efficient Rebroadcast For Reducing Routing Overhead In Manets

Abstract: Mobile Ad Hoc NETwork is a wireless network formed by wireless nodes without any help of infrastructure. In this network, nodes are mobile and can communicate dynamically in an arbitrary manner. The network is characterized by the absence of central administration devices like base stations and access points. One of the fundamental challenges in Mobile Ad Hoc NETwork is to discover the route with good performance and less overhead. The overhead of a route discovery cannot be neglected. Limiting the number of rebroadcasts can optimize the broadcasting. Enabling efficient rebroadcast for reducing routing overhead in Mobile Ad Hoc NETwork is used to reduce the number of retransmissions and routing overhead. The probabilistic rebroadcast algorithm is used to calculate the Covered Neighbor set and UnCovered Neighbor set for broadcasting. Broadcasting based on probabilistic rebroadcast algorithm can effectively discover the route by using the additional coverage ratio and connectivity factor. Simulation results are demonstrated using NS-2 Simulator. From these results, the proposed system significantly decreases the number of retransmissions, routing overhead and increases the routing performance
