摘要
无线传感器网络是由部署在监视区域的大量微型的具有无线通信及计算能力的传感器节点,以无线多跳通信方式构成的分布式自组织网络系统。它能根据环境需要,通过功能有限的传感器节点之间的协同工作,对监控区域内的环境或监测对象的信息进行实时感知、采集和处理,获得详尽而准确的侦测数据。本文主要分析无线传感器网络中的定位技术,研究如何降低网络中的能量消耗,延长网络寿命。
Wireless sensor network is a multi-hop self-organized network system that consists of a large amount of low-cost ,low-power and small size sensor nodes with limited sensing ,computing and communication capabilities which can communicate with each other to perform sensing adn data processing. This paper analyzes the existing algorithms about localization problems in wireless sensor network. Then it researches on how to reduce the energy consumption of network and extend the network life.
