In wireless sensor networks (WSN), sensor nodes just can use battery as their power resource and the power is quite limited. So, energy efficiency research is the key issue in design reasonable wireless sensor network routing protocols. In the paper, a revised cluster election method named LEACH-PSOv has been proposed to strengthen the hierarchical routing protocol low energy adaptive clustering hierarchy (LEACH). In the algorithm, particle colony optimization has been used to divide the

The algorithm proposed can be effectively to extend the lifetime of the networks. The simulation results show that the life time with new algorithm can extend the lifetime. Based on the improved LEACH algorithm, environmental monitor system has been designed.
