As the demands for better quality of service (QoS) increases, requirements for high fairness performance for a short periods of time are also arisen in the Wireless Local Area Network (WLAN). Although the IEEE 802.11 Distributed Coordination Function (DCF) is the most widely used in WLAN, relatively little attention have been paid to improve the short-term fairness of the IEEE 802.11 DCF. In this study, we propose a simple random access protocol as an alternative of the IEEE 802.11 DCF, called the renewal access protocol, where each terminal selects a back off counter value from a priori probability distribution, called the selection distribution. We mathematically model the successful packet transmission behavior by delayed renewal process. And then we use this modeling and the Jain’s fairness index to measure the extent of short-term fairness. We conjecture that the short-term fairness is considerably affected by the variance value of selection distribution. This behavior is verified through numerical and simulation studies.
