A QoS tracking algorithm for multimedia requirements over IEEE 802.11e multihop networks

In this paper, we propose a QoS tracking algorithm to support different QoS requirements to accommodate delay-sensitive and throughput-sensitive traffics in wireless mesh networks. The proposed scheme is carried out in a totally distributed manner by adjusting the minimum contention window size. Moreover, we investigate whether we can satisfy all QoS requirements in a stable manner through stability analysis. The simulation results show that the proposed algorithm can satisfy both average delay bound and minimum throughput requirements without sacrifice of total system efficiency.
