摘要
正确的节点位置信息是无线传感器网络许多功能模块实现的前提和基础,如网络构建和维护、监测事件定位、目标跟踪。在资源受限的传感器网络中,如何安全和有效地获取节点位置信息,是一个极具挑战性的安全问题。本文着重分析了不同的传感器节点定位系统所面临的各种攻击,分析了近年来该领域具有代表性的安全措施的原理、特点和局限,并简要介绍了该领域今后的研究热点。
Correct node location information is the prerequisite and foundation of many wireless sensor network modules, such as network building and maintenance, monitoring event localization, and target tracking. In resource-constrained sensor networks, how to securely and effectively position sensor＇s coordinates is one of the most challenging security problems. This paper presents various attacks against different node localization systems, analyses the principles, characteristics,and limitations of recent representative secure localization countermeasures. Finally, the future research direction is summarized.
