Abstract

IEEE 802.11, which is one of the most widely used wireless LAN standard protocol, employs binary exponential back-off (BEB) for reducing packet collisions. Although the BEB can avoid effectively packet collision by a simple mechanism, transmission unfairness arises under the high traffic environment and/or inequality of numbers of neighboring terminals situation. This paper discusses about relations between unfairness and aboves, and proposes a method of frame-burst transmission with adaptive and autonomous controlling for improving fairness in keeping compatibility with legacy IEE E802.11 DCF terminals. From the results of computer simulations, it is reported that our technique improves fairness effectively with no performance degradation
