摘要: 针对DV-Hop非测距定位技术没有考虑非法节点(包括无法定位的节点)对定位过程影响的问题,提出了一种基于DV-Hop的安全定位机制,即在定位过程中引入了节点间交互信息特性用于检测虫洞攻击,利用时间性质和空间性质明确有效信标节点,并且结合在节点通信过程中加入加密和认证机制来抵御伪装攻击,最后实现安全定位。仿真实验表明,在攻击存在的环境中,提出的安全定位机制能够以较高的概率检测出虫洞攻击,并使定位误差减小了大约63%左右。

Abstract: Concerning the problem that the impact of illegal nodes (including the node unable to locate) on the localization process in DV-Hop localization algorithm has not been taken into consideration, this paper proposed a secure localization mechanism based on DV-Hop. In other words, the character of message exchange between the nodes was introduced to detect the wormhole attacks in this paper. Time property and space property were used to define the valid beacon nodes, along with encryption and authentication mechanisms to resist against the node-tampering attack in the communication process. Finally, the nodes were located securely. The simulation results show that, in hostile environment, the proposed mechanism has a high probability to detect the wormhole attacks, and the relative localization error can be reduced by 63% or so.

Key words: Wireless Sensor Network (WSN), DV-Hop localization, wormhole attack, node-tampering attack, security location
