Abstract:

In this paper we profound a new process of integration of three layers such as MAC layer (Medium Access Control) which is sub-layer of Data Link layer, Transport layer and Network layer and the linkage of DSR (Dynamic Source Routing) Protocol. The ultimate goal of using cross layer approach is to find efficient energy utilization and for reducing the link failure problem. This delay in the MAC layer is a problem and which is not discussed in our existing method. With the help of Contention RTT (Round Trip Time) and Congestion RTT, the delays in the MAC layer and Transport layer can be monitored and the average delays will be calculated, and obtain a threshold value for each and every hop. We define a parameter known as VCR (Variance of Contention RTT) to improve the throughput performance. We propose a novel mechanism known as Contention Window based Congestion Control (CWCC) Algorithm which eliminates the congestion problem. The performance of the proposed scheme is evaluated by ns-2 simulators and the simulation results show the improvements acquired through our approach in terms of speed, delay and throughput performance.
