Wireless sensor network has attracted considerable research attention, as the world becomes more information oriented. Routing metric is becoming an important research topic. This paper firstly makes a summary to the existing routing metrics, accordingly analyzes that it is deficient to design routing protocols for wireless sensor networks based existing routing metric. Secondly, finds the several key characteristics of wireless sensor networks communication link, according to the experimental study. From these, optimize power routing metric is provided. Finally, the routing metric proposed in the paper is adopted to improve the traditional directed diffusion routing protocol. Simulation results show that the optimization transmit power can greatly improve network life compared with transmit power, which plays the important instructing role for wireless sensor network.
