A New Malicious Node Recognition Algorithm for Wireless Sensor Networks

A key issue to protect the network security is whether be able to identify the malicious nodes inside the wireless sensor network. In this paper, we discuss the technique of identifying the malicious nodes by using the known reputation information of the nodes, and propose an algorithm to identify the malicious nodes of the network based on the node reputation time sequence analysis. The algorithm introduces the idea of time sequence analysis into the reputation security mechanism of wireless sensor networks, and uses a series of analysis operations on the node reputation data to identify and judge the malicious nodes in the network. Experimental results show that the algorithm is effective.
