End to End Delay Improvement Using Multipath Routing in MANET
Journal Title: International Journal of Advanced Research in Computer Engineering & Technology(IJARCET) - Year 2012, Vol 1, Issue 7
Abstract
Congestion and the loss of energy is the most common problem in the Ad hoc network. A considerable amount of energy is consumed in wireless interfaces. On the other hand the actual available bandwidth varies due to change in contention affected by node mobility. Many of routing protocols use the shortest path route from source to destination with minimum hop count as optimal route selection. But minimum end to end delay may not always achieved through shortest path because of high collision rate and flows at the intermediate nodes. In this paper we propose an improvement of end to end delay using multipath routing which determines the best path selection out of the N-available shortest paths by considering congestion and energy constrains at each of the intermediate nodes. Contention window along with buffer size at MAC layer affects successfully transmission of packets. Performance results show that increase in the PDR, throughput and decrease of overhead and latency when compared to AODV. The proposed method improves the performance of network
