摘要:

针对无线传感器网络(WSN)中存在的节点捕获攻击,提出了一种节点捕获检测方法.该方法利用序贯概率比检验检测出网络中的捕获节点,并结合控制理论对网络进行控制,利用离散系统二次型性能指标的最优控制,获得网络控制下的最优控制序列,以实施对网络的最优控制.仿真结果表明,本方法能够检测出网络中捕获节点,并通过不断对网络实施控制,使网络状态渐近稳定.

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
