Abstract

With the rapid popularization of wireless communication devices, wireless local area network (WLAN) is ubiquitous in daily life. However, the demand for wireless communication services is growing rapidly and brings new challenges to WLAN technology. The problem of performance degradation under dense deployment network scenarios is an important topic in the next generation WLAN (NGW). This paper proposes fractional backoff algorithm, named eat-B, to enhance area throughput. Eat-B introduces fractional backoff and enables the nodes who provide more contributions for the area throughput to finish their backoff process faster. Simulation results indicate that the area throughput of the eat-B algorithm outperforms the binary exponential backoff (BEB) algorithm adopted by the traditional IEEE 802.11, especially under dense deployment scenarios.
