Abstract: This paper analyzes LEACH protocol, pointing out the shortcomings in the selection of cluster heads and communication between cluster heads and base station. For the lack of LEACH, it starts form balancing energy consumption and saves energy, proposes an improved LEACH protocol named LEACH-EB. Simulation results show LEACH-EB can effectively save energy, balance energy consumption and prolong the network life cycle.

Key words: WSN, LEACH protocol, energy-balancing, cluster head selection, inter-cluster routing

摘要： 分析LEACH协议，指出其在簇头选择、簇头与基站通信方面存在的不足。针对上述问题，以均衡能耗和节省能量为出发点，结合LEACH-C的特点及Dijkstra算法对LEACH协议进行改进，提出LEACH-EB协议。仿真结果表明，LEACH-EB协议能有效节省能量，均衡能量消耗，延长网络生命周期。
