摘要
低成本、低能耗和高效益是无线传感器网络研究的核心问题,也是其网络性能重要参数,提高能量有效性是无线传感器网络设计的主要目标之一,有效利用传感器节点来延长网络寿命是近期研究的热点。研究了无线传感器网络中部分相关数据的数据融合对分簇网络的影响,研究结果表明节点的能量消耗在很大程度上取决于节点的位置,网络的总能量消耗与寿命之间有一个折中。
Wireless sensor networks(WSN)research focuses on low cost, low consumption and high efficiency, which are also important parameters for network performance. One of the main objectives of wireless sensor network design is to improve the energy efficiency. How to efficiently utilize sensor nodes to pro- long the lifespan of a wireless network has long been a research topic. This paper deals with the influence to relevant data fusion on clustering network in WSN. According to the results of the study, the nodes' energy consumption largely depends ori their location. The results further show that there is a trade-off between the total energy consumption of the networks and the network lifetime, if the total energy consumption of the networks reaches its minimum, the network lifetime is not necessarily the longest.
