Performance Evaluation of Backoff Method -- Effect of Backoff Factor on Exponential Backoff Algorithm

In this paper the effect of back off factor on exponential algorithm is analyzed and binary exponential algorithm is implemented in Mat lab. Binary Exponential Algorithm is widely used as a network congestion avoidance or collision resolution protocol. The detailed analysis of saturation throughput is done in this work. This work also covers packet's medium access delay for a given number of node N. Binary exponential is a special case of exponential back off when r =2, where r is a back off factor and we basically analyse the effect of back off factor r =1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2.0 on exponential back off algorithm. All the result is obtained through Matlab (Matrix Laboratory) simulation language.
