为了实现无线传感器网络(WSN)中能量的高效利用从而延长网络寿命,结合已有的研究,讨论了无线传感器网络中引起能量浪费的主要原因,总结并详细阐述了现有的用于无线传感器网络中的几种主要节能策略,如休眠机制、数据融合机制以及冲突避免机制等。对这些策略的分析表明使用节能机制可以有效地降低能耗。最后针对当前节能方法面临和需要解决的关键问题,提出了对节能策略研究趋势的几点设想。
In order to realize the efficient use of energy in Wireless Sensor Network (WSN) and prolong the lifetime of network, this paper discusses the main causes of energy waste in Wireless Sensor Networks (WSNs) and summarizes the main existing problems in Wireless Sensor Networks In several major energy-saving strategies, such as sleep mechanism, data fusion mechanism and conflict avoidance mechanism. Analysis of these strategies shows that the use of energy-saving mechanisms can effectively reduce energy consumption. Finally, in view of the key issues that the current energy-saving methods are facing and need to be solved, some ideas about the research trends of energy-saving strategies are put forward.
