Improvement and Performance Analysis of DSR Protocol in MANET

Abstract

The characteristics and shortcomings of dynamic source routing protocol (DSR) in mobile Ad hoc network are analyzed in detail. For the DSR protocol did not consider the network load, node energy and optimal path problems etc. proposed a new and improved DSR protocol, LEBDSR (Load and Energy Balanced Dynamic Source Routing) protocol, it increased the node congestion factor and energy coefficient based on the original protocol, and improved routing strategy under the new constraint parameters. By comparative analysis of NS-2 simulation, performance of the proposed DSR protocol such as the delivery rate, routing load, network minimum survival time were improved in the same network environment.
