Abstract:

Aiming at the disadvantage of node capture attack that exists in the WSN(Wireless Sensor Network), we presents a node capture detection method using SPRT(Sequential Probability Ratio Test) to detect capture nodes, and regulate the network by control theory tools. The optimal control sequence is accessed by optimal control of discrete system quadratic performance index. Simulation results show that this method can detect the capture nodes, and that the network status becomes asymptotically stable through continuous implementation of network control.

Key words: WSN, node capture attack, detection, control
