“…WMN is also the suitable access solution of last mile. However, compared with wired network, the channel of wireless networks cannot provide a guaranteed link, and there also exists asymmetric, immediate loss and transmission error (bit error) in wireless networks [ 1 ]. From the research in [ 2 ], data packet loss is not caused only by distance and signal attenuation; SNR (Signal-to-Noise Ratio, S/N) and multipath fading with interference are also the important reasons which lead to packet loss.…”

WMN (wireless mesh network) is a useful wireless multihop network with tremendous research value. The routing strategy decides the performance of network and the quality of transmission. A good routing algorithm will use the whole bandwidth of network and assure the quality of service of traffic. Since the routing metric ETX (expected transmission count) does not assure good quality of wireless links, to improve the routing performance, an opportunistic routing mechanism combined with long-term and short-term metrics for WMN based on OLSR (optimized link state routing) and ETX is proposed in this paper. This mechanism always chooses the highest throughput links to improve the performance of routing over WMN and then reduces the energy consumption of mesh routers. The simulations and analyses show that the opportunistic routing mechanism is better than the mechanism with the metric of ETX.
