| 摘 要： | 针对于直接传输（DT，DirectTransmission）和最小化传输能量（MTE，MinimumTransmissionEnergy）两种传统通信协议的缺点和无线传感器网络（WSNs，WirelessSensorNetworks）的特点，分析了基于分簇的无线传感器网络通信的低功耗自适应分簇协议（LEACH，Low—EnergyAdaptiveCluste—ringHierarchy）的基本原理，并对三者进行仿真分析。分析与仿真结果表明，使用LEACH协议比使用DT协议要节约大约7到8倍的能源，同时也比MTE协议方式要减少4到8倍能源消耗。更适用于无线传感器网络。

| Abstract: | Two traditional communication protocols, including DT（ direct transmission protocol） and MTE （minimum-transmission-energy routing protocol） , are analyzed. Due to the flaws of these two protocols and based on features of wireless sensor network, an clustering communication protocol for WSN, that is, LEACH （Low-Energy Adaptive Clustering Hierarchy）, is proposed. Then simulation and analysis on these three protocols indicate that LEACH could achieve a reduction of between 7x and 8x in energy con- sumption as compared with DT,and of between 4x and 8x with MTE routing, this would be more saitable for wireless sensor network. |
