The energy constraint and the low power communication requirements amplify the significance of the energy efficient routing protocols in wireless sensor networks (WSNs). The primary aim to design a routing protocol for WSN is to improve the energy efficiency and prolong the network lifetime. In this paper, we propose a cluster-chain routing protocol (CCRP), which adopts a more balanced cluster-head selection algorithm and an improved data transmission mechanism from the cluster-heads to the base station. Simulation results indicate that, for a 100m×100m network with the initial energy 0.5J in each node, the proposed CCRP outperforms LEACH by about 78%, 150% and 130% in terms of rounds when 1%, 50%, and 100% of nodes die, respectively.
