【摘要】：针对无线传感器网络中距离无关的定位技术,提出了DV-Hop定位中普通节点被俘获的欺骗攻击模型,分析了这种欺骗攻击模型对DV-Hop定位过程的影响,进而提出了一种抵御欺骗攻击的DV-Hop安全定位算法。首先,在普通节点端提出了基于发送-转发信息一致性的检测机制来检测恶意节点;其次,在汇聚节点端提出了基于消息转发链举证的检测机制来确定恶意节点;最后,当汇聚节点检测出存在恶意节点进行篡改攻击后,汇聚节点通报全网弃用恶意节点转发的数据分组并重启定位。仿真结果表明,本文提出的安全定位算法可以有效滤除恶意节点,且安全定位算法的定位性能与无攻击下的DV-Hop定位性能基本相当,可以有效解决欺骗攻击对DV-Hop定位过程造成的影响。
[Abstract]:Aiming at the range-independent localization technology in wireless sensor networks, a spoofing attack model of common nodes in DV-Hop localization is proposed. This paper analyzes the influence of this spoofing attack model on the DV-Hop localization process, and then proposes a DV-Hop security localization algorithm to resist spoofing attacks. A detection mechanism based on the consistency of sending and forwarding messages is proposed to detect malicious nodes at the common node end. Secondly, a detection mechanism based on message forwarding chain is proposed to determine the malicious node at the sink node end. Finally, when the convergence node detects the malicious node for tampering attack, the convergence node informs the whole network to discard the data packet forwarded by the malicious node and restart the location. The simulation results show that. The security location algorithm proposed in this paper can effectively filter out malicious nodes, and the location performance of the security location algorithm is basically the same as that of DV-Hop location without attack. It can effectively solve the influence of spoofing attack on DV-Hop localization process.

【正文快照】： 无线传感器网络(WSN)在军事、工农业控制、环境监测等相关领域有着广阔的应用前景。在大多数应用中,WSN监测的事件与节点的物理位置信息息息相关,没有位置信息的监测数据是毫无意义的。因此,节点定位技术[1-2]作为WSN的应用基础,贯穿了整个WSN技术的研究和发展。WSN节点定位大
