论文摘要
在本文中，我们研究了在存在拒绝服务（DOS）攻击下将传感器位置定位的问题。我们考虑了一个通用攻击模型，其中仅通过DOS攻击的频率和持续时间来限制攻击者的动作。我们提出了一种分布式迭代定位算法，具有基于传感器的邻居的barycentric坐标的放弃策略，该算法是通过相对距离测量来计算的。特别是，如果传感器的通信链接用于接收其邻居信息，则由于DOS攻击而丢失了数据包，则传感器放弃了位置估计。当攻击者发射DOS攻击时，理论上证明AS-DILOC算法能够准确地定位传感器，而不管每次攻击策略如何。通过模拟示例证明了所提出算法的有效性。
In this paper, we study the problem of localizing the sensors' positions in presence of denial-of-service (DoS) attacks. We consider a general attack model, in which the attacker action is only constrained through the frequency and duration of DoS attacks. We propose a distributed iterative localization algorithm with an abandonment strategy based on the barycentric coordinate of a sensor with respect to its neighbors, which is computed through relative distance measurements. In particular, if a sensor's communication links for receiving its neighbors' information lose packets due to DoS attacks, then the sensor abandons the location estimation. When the attacker launches DoS attacks, the AS-DILOC algorithm is proved theoretically to be able to accurately locate the sensors regardless of the attack strategy at each time. The effectiveness of the proposed algorithm is demonstrated through simulation examples.
