无线传感网络能量高效的协议综述

Review on energy-efficient protocols in low-duty-cycle wireless sensor networks

无线传感器节点能够实时监测和采集监测区域内目标的信息,并将数据上报给汇聚节点。然而节点一般由电池供电,能量受限,如何降低能量消耗、提高网络寿命成为无线传感网络的关键技术。本文从MAC协议、数据融合协议和路由协议三个方面论述了目前国内外有关能量高效使用的研究成果,并分析了目前国内外具有代表性的基于能量的协议及算法。

The sense nodes in wireless sensor networks are capable of monitoring the target in the monitor area all the time, and send the sensed data to the sink node. However, the nodes are generally charged by the battery, and have limited energy resource, Therefore, how to improve energy efficiency and extend the network life is a foremost concern for wireless sensor network. The paper reviews the current main design strategies in MAC layer, data ag-gregation and routing based on the energy saving, and presents a comprehensive overview of different approaches for MAC layer protocol, data aggregation protocol and routing protocol.
