Neural network-based intrusion detection algorithm for wireless sensor network

Abstract

The invention simply discloses an intrusion detection model by combining the existing network intrusion detection technology aiming at cluster heads (Cluster Head, CH for short) of a cluster-based wireless sensor network (Cluster-based Wireless Sensor Network, CWSN for short). The characteristics of low CH operating rate and limited energy are fully considered; the designed model is simple in structure, and composed of the following three modules: a misuse detection module, an abnormality detection module and a decision module, wherein the misuse detection module utilizes the neural network as a core. The existing neural network is various in variety and each neural network has advantages and defects, a back propagation (BP) neural network, a generalized regression neural network and a BP neural network optimized on the basis of a genetic algorithm are respectively selected to carry out an experiment to obtain the neural network which is more suitable for an intrusion detection system (IDS) aiming at a wireless sensor network (WSN). The experiment adopts a KDDCUP1999 data set, and a matrix laboratory (MATLAB) is utilized to carry out a simulation experiment.

Description

technical field [0001] The invention relates to an intrusion detection algorithm of a wireless sensor network, in particular, an intrusion detection algorithm of a wireless sensor network based on a neural network. Background technique [0002] Intrusion detection research can be traced back to 1980, when James P. Anderson first proposed the concept of intrusion detection. In 1987, Dorothy Elizabeth Denning proposed the abstract model of intrusion detection system, and first put forward the concept of intrusion detection as a strategy of computer system security defense. Compared with traditional encryption and access control methods, intrusion detection system is a new computer security strategy. At present, there are three main development trends of intrusion detection technology at home and abroad: distributed intrusion detection, intelligent intrusion detection and the trend of combining with network security technology. However, the research on applying intrusion dete...
