| 摘 要： | 无线传感器网络中路由协议最重要的设计目标是延长网络生存时间.基于已有的LEACH协议,融入了负载平衡和备用节点的思想,让备用节点尽量处于睡眠状态,对LEACH协议进行了改进.分析与仿真结果表明,当节点密度较大时,改进协议保证了簇的规模在整个网络中合理均匀的分布,并可显著地延长网络生存时间. |
| 关 键 词： | 无线传感器网络 LEACH协议 备用节点 网络生存时间 负载平衡 |

| Abstract: | Prolonging the lifetime of the network is the primary goal for routing protocol design in wireless sensor networks. Based on the analysis of the existing LEACH protocol, the improved protocol is proposed, which concerns with load balance and spare nodes and makes spare nodes to live on the dormancystate. Analysis and simulation results show that, the improved protocol can ensure the reasonable and equable distribution of cluster scale in the networks, and then prolong the lifetime of the network effectively when density of nodes is larger. |
| Keywords: | wireless sensor networks LEACH protocol spare nodes the lifetime of the network load balance |
