Study on Automatic Positioning of Malicious Mobile Nodes in Wireless Sensor Networks

Abstract

Abstract. The automatic positioning method of malicious mobile nodes in wireless sensor networks is one of the security content of wireless sensor networks, which has the extremely important research significance. In the traditional wireless sensor networks, the location of the malicious mobile nodes needs to be provided support by the regional monitoring of the nodes under attack. The power consumption and cost are greatly limited. Therefore, we proposed a fuzzification malicious mobile node positioning algorithm, which was based on the existing network node positioning function and the MONTE CARLO positioning algorithm. It filtered the periodical information for fuzzy processing, which could still be highly accurate positioning under the asking with smaller communication data. The simulation results show that the proposed method is simple, the interface and port are uniform, and the computing speed and positioning accuracy are improved.
