无线传感器网络的部署

Deployment in wireless sensor networks

传感器节点的部署是无线传感器网络中的很重要的问题,因为它反映了传感器网络的成本和监视能力。它和定位、跟踪一样,是无线传感器网络中的一个基本的问题。尽管国外已经在这方面开展了一些相关研究,由于不同的应用有不同的部署特点和目标,仍然面临很多挑战。综合大量无线传感器网络部署相关的技术文献和最新研究结果,着重分析无线传感器网络中节点部署问题的重要性、面临的主要挑战、研究的现状以及对已有算法优缺点的剖析,指出下一步的研究方向。以环境监测中部署算法的设计为例,指出关键的考虑因素。

The deployment of the sensors is of importance in WSNs, it reflects the cost and the capability of monitoring. It becomes one of the fundamental issues following location and tracing. Although lot of research work have been conducted outside china,yet there are a number of challenges due to the different situation and goal in each application. Based on a lot of most recent published papers and research results the challenges, research status and the advantage and disadvantage of some existing algorithms are analysed. The possible future work for deployment algorithm is pointed out. Taking the design in environment monitoring as example, the important part is discussed.
