Abstract

Abstract: The environmental pollution is a problem which must be resolved in the course of the continuous economic development， it is specially necessary how to take the effective and convenient steps to monitoring environment.A remote environmental monitoring system with wireless sensor networks is designed.To solve the frequent changes of energy and the easily occurring“energy hole”problem，the mobile sink is employed.Experiment results show that the environmental monitoring system based on the mobile sink can prolong the network life time，and ensure the average energy consumption of each node. And the network packet loss rate and delay close to the environmental monitoring system based on the fixed sink.

Key words: environmental monitoring system, Wireless Sensor Networks（WSNs）, mobile sink, energy hole

摘要： 环境污染是可持续经济发展中必须解决的问题，如何采取高效、便捷的方法监测环境显得尤为必要。设计了一种基于无线传感器网络的远程环境监测系统，并采用移动汇聚节点的方法，解决节点能量更换频繁且容易产生的“能量空洞”问题。实验结果表明，基于移动汇聚节点的环境监测系统能够延长网络的生命周期，确保各个节点的能量消耗均衡，并且网络整体数据包丢失率和时延与固定汇聚节点的监测系统接近。
