Prolonged lifetime, improved coverage, and load balancing are important requirements in wireless sensor network applications. In this paper, we propose a new clustering protocol聳adaptive clustering algorithm based on energy restriction (ACAER), which periodically selects cluster nodes according to their coverage rate and residual energy. ACAER has no assumptions about the distribution or density of nodes, or about the placement area of nodes. The result of tests shows that, compared with other protocols (such as LEACH, HEED), the ACAER protocol can effectively improve coverage and balance load of the nodes to prolong the lifetime of networks. The standpoint in this paper attributes to utilizing the linearization PRI algorithm to improve clustering algorithm. The achievement can be applied to not only the adaptive route algorithm based on clustering, but also the scalability of WSN protocols.
