基于能量节约的无线传感器网络覆盖优化探讨

Discussion on the Coverage Optimization of Wireless Sensor Networks Based on Energy Saving

在无线传感器网络研究中,功率控制是一项重要的议题。Tian和Georganas找出被覆盖的传感器冗余节点,将传感器节点进行睡眠的调度,以延长无线传感网络的寿命。本研究以Tian和Georganas提出的方法作为研究基础,做出改进。提出了改良分散式覆盖传感器判断法。在兼顾监测范围完整性的前提下,可以达到更省电、更长网络寿命的效果。

Power control is an important issue during the research of the wireless sensor networks.Tian and Georganas discovered the sensor nodes which have been covered completely,putting the sensor nodes enter the sleeping scheduling in order to lengthen the longevity of the wireless sensor networks.In order tomake improvement,the research is based on the methods put forward by Tian and Georganas,putting forward the judgment method of improving distributed Coverage sensor.In the presupposition of taking the integrity of sensing range into consideration,our methods can achieve the purpose of a more saving energy and a longer network lifetime.
