Based on the traditional LEACH protocol, an improved LEACH-CND protocol is proposed. The cluster head election of WSN network is optimized and implemented on the basis of residual energy, and the best cluster numbers of the wireless sensor networks is thus calsulated. Meanwhile, based on the ad-vantage of the elliptic curve cryptosystem, the lightweight identity key encryption algorithms for WSN node is explored. Finally, simulation on the optimized protocol in MATLAB environment indicates its feasibility, and that it could prolong survival time of WSN networks.
