无线传感器网络中虚假数据过滤方案

False data filtering scheme in wireless sensor networks

传统虚假数据过滤算法不能有效地应用于无线传感器网络,因而需要研究适合无线传感器网络的虚假数据过滤方案。在介绍无线传感器网络与虚假数据过滤的概念和特点后,提出了虚假数据过滤方案的分类方法,探讨了各种虚假数据过滤策略,着重分析了当前一些较为重要的虚假数据过滤策略,并指出了这些策略的优缺点。最后分析了当前亟待解决的问题,展望了其未来的发展趋势。

Traditional false data filtering cannot be applied efficiently to wireless sensor networks.Therefore false data filtering for WSN should be studied.After describing the concepts and characteristics of wireless sensor networks and false data filtering in the networks,this paper presented the classification standards for false data filtering.Then it analyzed the key mechanisms of the existing representative false data filtering,and pointed out the merits and demerits of them in detailed.In particular,this paper summarized the current research progresses.Finally,it also pointed out the open research problems.
