A New Approach For Reducing Routing Overhead In MANET

In MANET, the mobiles nodes are connected dynamically with the help of wireless links without having a fixed infrastructure or centralized administration. These nodes move freely and organize themselves arbitrarily thus change the network topology rapidly and unpredictably. As a result, there exits frequent link breakages which leads to path failures and route discoveries. The route discovery can lead to overhead which cannot be neglected. Therefore, the fundamental challenge of MANET is to develop a dynamic routing protocol that efficiently establish routes to deliver the packets with minimum overhead, high throughput and low end to end delay. In order to handle overhead issues, the proposed system has presented a novel scheme rebroadcast delay and a rebroadcast probability which will help to reduce the number of retransmissions thereby improving routing performance. In addition, the proposed system is compared with existing routing protocol AODV in terms of packet delivery ratio, packet loss and end to end delay.
