Performance Improvement of Routing Protocol in MANET  
  Authors : Namrata Chavan; Shilpa Verma


A Mobile Ad-hoc Network (MANET) is a self organizing and self configuring network without any centralized base station. Congestion and the loss of energy is the most common problem in the Ad hoc network. A considerable amount of energy is consumed in wireless interfaces. On the other hand the actual available bandwidth varies due to change in contention affected by node mobility. Many of routing protocols use the shortest path route from source to destination with minimum hop count as optimal route selection. This paper analyses and evaluates the mechanism using multipath routing for performance improvement. This mechanism determines the best path selection out of the N-available shortest paths by considering congestion and energy constrains at each of the intermediate nodes. A new mechanism based on contention window provides better performance compared to AODV.

In this paper, we present new approach to improve the overall performance using multipath routing in ad hoc network. As load increases in network, maintaining high packet delivery ratio and throughput is difficult. Excess control overhead is observed due to route maintenance. In order to overcome these problems, new contention based multipath routing is introduced. In proposed approach all paths are cached at the beginning only so that source select best multi-path route from source to destination based on cost matrix with maximum Contention Window.
