Abstract

The most known drawback of IEEE 802.11 MAC is the low performance in terms of throughput in case of congested networks. Backoff time is one of the most important factors that govern the collision probability in Ad-Hoc network. Using backoff algorithm could push the performance up and decrease collision rate. This study presents an enhanced fibonacci backoff Algorithm (EFB) for Ad-Hoc Network in which contention window size is selected from two choices: linear and Fibonacci. Simulation results show high performance and less average of end to end delay especially at high number of nodes compared to Binary Exponential Backoff algorithm (BEB).
