The main design challenges of the wireless sensor network is to obtain long system lifetime, as well as maintain sufficient sensing coverage and reliability. In this paper, a novel node-scheduling algorithm based on grade field model is presented. The grade transition algorithm in different grade field is depicted and analyzed. This algorithm can decrease network traffic and avoid additional cooperative time waste. By using this algorithm, the energy of the sensor nodes can be consumed equably and also the system life of the network can be prolonged.
