摘　　要：针对无线传感器网络通信中能量消耗过高及电源极为有限、不可替换问题,设计了室内监控系统,布置Zig Bee无线网络,重点解决延长网络生命周期问题。针对LEACH算法中所有节点轮流充当簇首消耗能量过多问题,提出每轮第一次充当簇首的节点全程有效,即FL方法。该算法减少节点竞争簇首时消耗的能量。依据监控系统实际使用环境,结合LEACH(Low Energy Adaptive Clustering Hierarchy)算法分析通信过程中能量的消耗,设计验证实验,提出监控系统通信算法。实验证明,网络稳定,系统能耗低,通信性能良好,可用性强。Aiming at the problems of high energy consumption, limiting power supply and not replace in the process of the wireless sensor network （WSN）communication, the interi^or monitoring system is designed. ZigBee wireless network is organized. The key issue is to extend network life cycle. According to the actual use environment, the cluster head is effective in the entire which is projected in the first round because it consumes too much energy that all the nodes act as the cluster head in turn according to the LEACH （Low Energy Adaptive Clustering Hierarchy） algorithm. The method is named as FL. According to the practical using environment, energy consumption is analyzed about the communication combining with LEACH algorithm. Experiments has shown that networks are stable, the system energy consumption is low, and network telecommunication has excellent performance. The usability of the system is strong.
