基于TDoA测距的传感器网络安全定位研究

Research on TDoA-based secure localization for wireless sensor networks

针对基于TDoA测距的定位技术,分析了基本虫洞攻击与一贯虫洞攻击的特点,提出了一种利用无线多跳网络时空特性与测距数据一致性性质的攻击检测方法,并从理论上给出了此方法的成功检测攻击概率下限值。仿真结果表明提出的检测方法在各种网络参数下均优于已有的方法。

Basic wormhole attack and accordance wormhole attack problems were analyzed, based on which proposed an attack detection scheme. The lower bound of the detection probability stemming from this scheme was presented theoretically. Simulation results demonstrate that the proposed scheme achieves better performance than most existing approaches under the same network parameters.
