Dynamic Queue and TCP New Reno based Multipath Load Balancing Congestion Control Scheme for Mobile Ad Hoc Networks (MANET)

Abstract

In Effective load balancing has been a difficult task in Mobile Ad hoc Networks (MANET) due to their frequent change in topology. Multipath routing are providing the alternative path that is identified from source to destination using intermediate nodes that have better communication and processing capabilities to take part in the mobile routing and efficiently participate in the routing process but only multipath are not sufficient for handle congestion in network because it only provides the alternate path not provides the effective load balancing in network. This paper presents a new congestion control scheme based on multipath routing for enhanced load balancing in MANET. This scheme enhanced load balancing from dynamic queue length method that improves the store and forwarding capacity of nodes in network and to maintained queue size data rate of sender are controlled by that the TCP New Reno scheme. The combination of these two approaches provides better performance and congestion control according to current network traffic levels and nodes' processing loads. The proposed scheme performance are evaluate AOMDV performance and observed that the performance of proposed scheme showing the zero packets loss in terms of queue length and also minimizes the congestion. The performance is also measured on the basis of performance metrics like routing overhead, delay and the whole simulation is done in ns-2 simulator.
