A throughput efficiency oriented opportunistic routing algorithm for wireless Mesh networks is proposed. The relationship between the qualities and quantities of forwarding nodes is researched. The forwarding characteristics of multi-forwarders are analysed. Consequently,a new routing metric and a corresponding forwarder selection algorithm is presented successively. With this method, we will achieve a better balance between the number of forwarders and link stability for introducing the factor of transmission time. Simulations show that the proposed algorithm can achieve higher end-to-end throughput with fewer number of forwarding nodes and transmissions.
