Abstract: Part of the wireless Mesh network nodes are powered by the battery, and when wireless Mesh network is widely applied into wireless access, energy-saving is a significant work. This paper puts forward an energy-saving cluster-based routing protocol for wireless Mesh network (ECRPWMN), it firstly separates the network into some clusters, and runs the table-driven routing between the clusters; how much routing work the node in the cluster does is decided by how much residual energy it has, so as to achieve a balance of energy consumption. The simulation shows ECRPWMN can effectively save energy, balance network load and extend the network’s lifetime.
