摘要
为了改善注入式攻击下传感器网络的分布式滤波性能,并且解决网络通信传输过程存在的能量受限问题,设计了一种带有通信触发机制和攻击检测的分布式滤波算法.通过对传感器节点先验估计数据与实际测量数据之间测量残差的研究,得出传感器节点在遭受注入式攻击时的检测条件,从而去除遭受攻击的数据,保证系统正常运行.传感器节点通过比较最近一次发送的数据与最新测量数据建立事件触发通信机制,决定是否向邻居节点发送数据.仿真结果表明,该算法的攻击识别率高达90%,在降低通信率的同时,仍能够改善系统运行的性能.带有通信触发机制和攻击检测的分布式滤波算法可用于解决存在能量受限和注入式攻击的分布式滤波问题.
To improve the distributed filtering performance of sensor networks under injection attack and solve the problem of energy limitation in network communication transmission process, a distributed filtering algorithm with communication triggering mechanism and attack detection was designed. By studying the measurement residuals between the prior estimated data and the actual measurement data of the sensor node, the detection conditions of the sensor node under injection attack were obtained, so as to remove the attacked data and ensure the normal operation of the system. The sensor node established an event-triggered communication mechanism by comparing the latest data sent to the neighbor node with the new measurement data to decide whether to send data to neighbor nodes. Simulation results show that the algorithm has a high rate of attack recognition up to 90% and can improve the performance of the system while reducing the communication rate. The distributed filtering algorithm with communication triggering mechanism and attack detection can be used to solve distributed filtering problems with energy limitation and injection attack.
