Abstract

The IEEE 802.11e EDCA standard was developed to guarantee the Quality of Service (QoS) requirements of the different traffic types (voice, video, data, etc.) in WLAN. However, several studies have shown that this standard performs poorly under heavy load traffic due to the high collision rate. On the other hand, EDCA was also used in the battery constrained devices. But, very few studies have tried to improve the energy-efficiency of this standard. For these reasons, we propose in this paper a Fuzzy-Logic-based (FL) mechanism to improve both energy-efficiency and traffic performance of the IEEE 802.11e EDCA, and also to favor real-time traffic when traffic load is heavy. The proposed FL-EDCA decreases the collision probability considerably, through a dynamic adaptation of the contention windows, using fuzzy logic controller. Our simulation results show that FL-EDCA outperforms EDCA by improving significantly energy-efficiency and traffic performance.
