无线传感网络覆盖算法的研究进展

Research progress of partial coverage algorithm in wireless sensor networks

为了进一步研究无线传感网络(WSNs)应用中的传感节点覆盖问题,对相关技术性能和研究进展进行了阐述:对WSN进行多维分类,给出全覆盖、部分覆盖的概念;着重分析近年来具有代表性的部分覆盖技术及其优缺点,并从覆盖度、节点分布特性、节点类型以及网络拓扑结构4个方面进行比较分析;最后,总结出部分覆盖技术的未来可能的研究策略与突破方向。

In order to further study on the coverage of deployed sensors in the application of WSNs,the paper discussed the related technology and development:the multidimensional classification of WSNs was given,and the concepts of full coverage and partial coverage were introduced;then the existing representative partial coverage algorithms for WSNs were summarized with their advantages and disadvantages,and the four aspects of coverage degree,distribution characteristics,sensor types and network topology were comparatively analyzed;finally,the possible research direction and trends of partial coverage algorithms were prospected.
