针对基于无线传感器网络的多集装箱监测应用中存在的能量有限问题,提出了一种基于LEACH分层路由协议的低功耗监测算法,并对传统LEACH协议进行了更符合该应用要求的改进,最后以监测网络生存周期和低能量监测器生存时间为指标进行了仿真对比.仿真结果表明,改进后的协议有效地提高了监测网络能量消耗均衡度,延长了网络生存周期.

Aiming to the energy constrain problem of container monitoring system based on wireless sensor network,a low power monitoring scheme is proposed based on cluster-based routing protocol LEACH,and LEACH protocol is amended to fit the structure of monitoring system, and then simulate life cycle of the monitoring network and the lifetime of low-energy monitoring. The simulation results indicate that the improved LEACH protocol efficiently makes a better utilization of network energy, and the lifetime of the whole monitoring network is enhanced.
