(English Abstract)
In this paper, we propose a QoS routing protocol for WiMAX based wireless mesh networks. The proposed routing protocol is a proactive hop-by-hop QoS routing protocol. It can find an optimal route that satisfies QoS requirements using bandwidth and delay as QoS parameters. In this paper, we first present a network model for WIMAX based wireless mesh networks and explain why QoS routing protocol is the most appropriate for WiMAX based wireless mesh networks. Then, we propose a proactive hop-by-hop QoS routing protocol that meets QoS requirements of traffic flowing between mesh client and the gateway. The simulation results show that the proposed routing protocol outperforms QOLSR protocol in terms of end-to-end delay, packet delivery ratio and routing overhead.
