摘　　要：无线传感网络是融合了传感器技术、信息处理技术和网络通信技术,成为对人们现在乃至将来生活方式产生重大影响的信息技术。由于传感器节点依靠电池供给能量,不易对如此众多的节点更换电池,网络生命周期就成为了无线传感器网络的关键性能指标之一。从能量均衡消耗角度的重点分析了TopDisc拓扑算法优缺点并在此基础上对TopDisc算法的对应改进。Wireless sensor networks is the integration of sensor technology, information processing and networking communications technology, will become a major information technology to change people's lifestyles. Due to the supply of sensor nodes rely on battery power, and not easy to replace so many nodes batteries, network lifetime has become one key performance indicators of the wireless sensor networks. In this paper, the contribution and innovation lies in-depth analysis the characteristics of the classic Topdisc algorithm and improvement of it from the energy equilibrium consumption angle.
