PERFORMANCE EVALUATION OF MULTIPATH ROUTING PROTOCOL IN MOBILE AD-HOC NETWORK

A Mobile Ad hoc Network (MANET) is a collection of wireless mobile nodes forming a temporary network without using any existing infrastructure. Due to the dynamic nature of the network topology congestion and load balancing are the major problem in Mobile Ad-hoc Networks routing. Most of the existing protocols provide solutions to load balancing or congestion or fault tolerance individually. In this paper a load balancing algorithms ( Balanced Multipath Source Routing ) is implemented and analysed. BMSR? protocol distribute the traffic load over multipath? route according to its minimum weight. The BMSR is implemented in NS2 and evaluate the performance based on metrics like throughput packet delivery ratio delay. The performance are measured and compared with existing DSR protocol. In this paper, the simulation results show that the BMSR algorithm solves the problem of congestion through load balancing in different scenarios through which BMSR outperforms DSR significantly.
