Research on intrusion detection algorithm based on specification for WSN
无线传感器网络中基于规范的入侵检测算法研究

To solve the security problem of wireless sensor networks, this paper proposed a kind of intrusion detection algorithm based on specification. The algorithm set threshold for characteristic quantity of neighborhood nodes in unit time accor-ding to the theory of probability. The method of threshold setting was versatile, and threshold could be updated adaptively to accord with the properties of sensor nodes changing over time. Compared the characteristic quantity in unit time from detection node with the threshold to judge invasion. Simulation results show the proposed algorithm is superior to other intrusion detection schemes based on specification, not only can meet high detection rates and low false positives, but also has good energy efficiency.
