Hierarchical routing protocols are critical for the wireless sensor networks (WSN) to maximize its lifetime, but the existing protocols are prone to lead nodes in clusters to die early due to ignoring the state of neighbors in the cluster head decision. In this paper, a new cluster-based optimization algorithm is set up which optimizes clustering process, to effectively avoid the low-energy and long-distance nodes as the cluster head. Considering sink node, The object cluster head routing protocol is proposed, it ensure that only the object cluster head send overall data to sink node, which can balance energy depletion among the cluster heads in WSN. The simulation results show that the optimization strategy significantly prolongs survival time of the network, the object cluster head routing protocol reduces the unbalance of cluster heads energy dissipation caused by different distance from Sink node and maximizes the network lifetime.
