| 摘 要： | 无线传感器网络是监控远程环境的工具之一.由于能量和存储空间的限制,其路由协议必须维持较小的路由信息并尽可能的减少能量消耗.基于经典的LEACH路由算法,提出了改进:主要体现在对能量和簇头间距的考虑上.最后用Matlab对LEACH算法和改进后的算法进行仿真,证实改进后的算法在网络生存时间和簇负载平衡程度上比LEACH算法有了很大提高.

| Abstract: | Due to the limitation of power and memory size, the router protocol of wireless sensor networks must maintain small router information and reduce the power usage as much as possible. The improvement of LEACH is based on power and distance between cluster head. Both of the algorithms were emulated in Matlab. The result of the emulation proves that the improved algorithm is much better than LEACH in lifetime and LBF. |

| Keywords: | wireless sensor networks dual-layer router algorithm LEACH lifetime LBF |
