Abstract:WMN (Wireless Mesh Network) is a useful wireless multi-hop network with tremendous research value. A good routing mechanism for WMN can use the whole bandwidth of the network and can assure the quality of service of traffic. Through simulations we verify that the routing metric ETX (Expected Transmission Count) cannot assure good quality of wireless links. To improve the routing performance, a QoS-assured opportunistic routing mechanism is proposed in this paper. This mechanism can choose the highest throughput links to improve the performance of routing over WMN and then reduce the energy consumption of mesh routers. The analyses show that the opportunistic routing mechanism is better than the mechanism with the routing metric of ETX.
