Load Balancing and Congestion Control using Congestion Aware Multipath Routing Protocol (CAMRP) in Wireless Networks

Abstract

This paper deals with a network-transparent wireless Here,we propose a congestion aware multipath routing protocol called CAMRP (Congetstion Aware Multipath Routing Protocol). The protocol computes multiple paths using proposed congestion aware metric and performs load balancing by a pooling scheme with proper queue utilization of variable interfaces of a node. However, the effective load balancing technique constantly maintains optimal data transmission using optimal path by managing traffic in all the way through congested area. Present Wireless Communications have got the popularity due to its randomness in the deployment and immense support and compatibility for different applications. Due to these applications, the problem of network congestion arises and in turn it results lower throughput and longer delay. In many recent research works, routing protocols dealing with these problems are designed but they are not sufficent to adapt congestion and optimal link quality. Our proposed woirk deals with this problem and the simulation results using ns2 proves that our proposed work on load balancing shows better performance than the existing in terms of throughput, end-to-end delay with heavy traffic load.
