Throughput and Delay Analysis of a RCO MAC Protocol Using ACW Technique in Ad Hoc Networks

In this paper, we present the performance analysis of the reliable cooperative media access control (Reliable Cooperative-MAC) protocol, in order to enhance system throughput in bad wireless channel environments, using Adaptive Contention Window. The performance of this protocol is evaluated with mat lab simulation as well as mathematical analysis. Here Adaptive Contention Window Algorithm is used to minimize collision and to improve performance of communication network. In addition, for performance evaluation two different traffic models are used: The saturated traffic model for computing system throughput and average channel access delay, and the exponential data generation model for calculating average system delay.
