IEEE 802.11 is a standard for wireless local area networks. Recent works show that this standard has bad performances in ad-hoc mode. In this paper, we analyze the algorithm used by the standard to manage contentions and propose an alternative algorithm to resolve fairness issues observed in the Hidden terminal scenario. Using NS-2 simulator we show that our algorithm has better throughput management based on fairness between nodes under QoS constraints required by each node.
