A Novel Adaptive Backoff Scheme for IEEE 802．11 Wireless Networks
In this paper.a new adaptive minimun contention window binary exponential backoff algorithm (referred to as AWBEB algorithm)is proposed to improve the performance of IEEE 802.11 Distributed Coordination Function(DCF)scheme,which is widely used for Ad Hoc networks and wireless LAN.We model the AWBEB algorithm scheme via establishing a bidimensional discrete-time Markov Chain,and the stationary distribution probabilities of AWBEB algorithm are derived.The performance of AWBEB algorithm is analyzed,and then AWBEB algorithm is simulated by computer programming.The analytical and nunlerical results show that the system saturation throughput and medium access delay of a packet for a given number of nodes N are better than the DCF algorithm.
