Abstract
The wireless sensor network is applied widely in many fields to monitor the service condition of the devices. However, due to the limit energy of the sensor nodes, the lifetime of the wireless sensor network becomes the vital factor to guarantee the stability and reliability of the system. In this paper, the cluster-based method is adopted to minimize the energy consumption of all the nodes and balance the energy consumption among all sensors to prolong the lifetime of the sensor network to the extreme. First, we calculate the optimal number of the clusters, ensuring the minimizing of the total energy consumption; and then we optimal the clusters based on K-means ++, guaranteeing the nodes close to each other are divided into the same cluster and decrease the energy consumption among the Non-Cluster Head nodes and Cluster-Head node. The valid of the strategy is verified in the following simulation, and the lifetime of the sensor network is increased noticeably.
