摘要
针对LEACH协议中簇首分布不均匀、簇首与基站之间只能采用单跳路径的缺点,通过对经典分簇路由协议LEACH的分析,采取改变簇首产生方式和簇首与基站之间的通信方式的方法 ,缩短了簇首的建立时间和通信距离,均衡了节点的能耗。仿真结果表明,该算法能有效地降低无线传感器网络节点的能量消耗,延长网络存活时间,提高传统LEACH算法的性能。
Aiming at the disadvantage of the uneven distribution of the cluster head and only single-hop path in the LEACH protocol, it reduces the setup time and the cluster head communication distance and balances the node energy consumption by analyzing the classic clumps and routing protocol LEACH and changing the way to produce cluster head and the communication way between the base station. The simulation results show that this algorithm can efficiently reduce energy consumption of wireless sensor network nodes, and make survival time of network much longer than traditional Leach algorithm.
