A Back-off Scheme for IEEE802.11 Wireless LANs

Abstract (in Japanese) (See Japanese page) 
(in English) Conventional IEEE802.11 wireless LANs employ the binary exponential back-off scheme to determine a back-off window size. Performance evaluations of the binary exponential back-off scheme and several enhanced ones have been done under an assumption that each station has a single transmission buffer. Under such assumption, enhanced schemes provide better performace, however they do not work well under a realistic condition that each station has multiple transmission buffer. In this paper, we propose a back-off scheme in which each station changes the back-off window size according to the load conditions. In order to evaluate performance of the porposed scheme, we build a queueing model and execute computer simulation. Simulation results show that the porposed scheme provides a higher throughput than the conventional ones.
