Research on Detection Method of Attack Traffic in Wireless Sensor Network Based on TF-IDF Algorithm
摘要
Abstract
There are many types of attack traffic in wireless sensor networks,and the detection method of attack traffic is difficult to meet multiple types of traffic data,resulting in poor detection accuracy.Therefore,a wireless sensor network attack traffic detection method based on TF-IDF algorithm is proposed.Firstly,the wireless sensor network traffic is divided into two type,i.e.,continuous and discrete.The continuous traffic is processed by using the unique heat coding,and the discrete traffic is normalized.Then,the traffic characteristics of the wireless sensor network are extracted by the TF-IDF algorithm,the multi-channel self-coder is trained by the feature vector set,and the TF-IDF algorithm is used to calculate the frequency of the attack traffic data characteristics to be detected in the wireless sensor net-work traffic,so as to sort the attack traffic.Finally,the final traffic type detection result is output through Softmax classifier.The simulation results show that the minimum detection precision of the proposed method is 97.05％,the maximum false alarm rate is 2.01％,and the av-erage test time is 20.1 s,proving that the proposed method can effectively and accurately detect attack traffic in wireless sensor networks.关键词
