| 摘 要： | 时空Top-k查询是TMWSNs（双层移动无线传感网）中的一类重要查询.在敌对环境中，攻击者易通过捕获TMWSNs中的关键节点来破坏时空Top-k查询的数据完整性.提出一种确保数据完整性的时空Top-k查询处理协议VIP-TQ.该协议利用虚拟化节点技术与绑定加密技术通过构建传感器节点的数据预处理方法、数据存储节点的时空Top-k查询处理方法以及Sink端的数据完整性验证方法来实现TMWSNs中时空Top-k查询的数据完整性保护.理论分析和实验结果显示，VIP-TQ能够以100%的概率侦测出不完整的时空Top-k查询结果，并具有相对已有方案更高的能效性.

| Abstract: | Spatio-temporal Top-k query results in TMWSNs (Two-tiered Mobile Wireless Sensor Networks) are facing threats.To preserve the integrity of the Top-k query results in TMWSNs,a novel integrity-ensured protocol named VIP-TQ is proposed for spatio-temporal Top-k queries in TMWSNs in this paper.VIP-TQ achieves integrity preserving for spatio-temporal Top-k queries by using several novel techniques such as node virtualization and binding encryption,and some novel methods such as the method of data pre-processing on the sensor nodes,the method of spatio-temporal Top-k query processing on the data storage node and the method of completeness verification on the Sink node.Theoretical analysis and simulation results show that VIP-TQ can detect the incomplete Top-k query results with probability 100% with high energy efficiency. |
