In this paper, several existing QoS (Quality of Service)-guaranteeing mechanisms for WiMAX mesh network (WMN) are analyzed, and the limitations of the existing mechanisms relating to the routing algorithms and the per-hop QoS guarantee are pointed out. Moreover, the reasons for the difficulty in guaranteeing the QoS are discussed, and an effective and dynamic QoS-guaranteeing algorithm for WMN is proposed. In this algorithm, WMN is considered as an integer to determine some constraints for the data packet processing of each WMN node in a view of integrity, and the traffic-handling algorithm for each node is presented. By using the proposed algorithm, the throughput of WMN is significantly improved and the fairness of bandwidth sharing by nodes is well guaranteed. Simulated results on a self-developed WMN platform show that the proposed algorithm is both effective and flexible.
