【摘要】 无线传感器网络的信道开放性很容易遭受干扰攻击,其中反应性干扰攻击隐蔽性高,检测难度大。分析总结了常见的无线传感器网络干扰攻击检测方法,提出了一种结合信号强度和重传率的一致性检测方法。利用CC2430节点通过实验证明该方法较目前常用的信号强度一致性检测方法,能更好地检测出反应性干扰攻击。更多还原

【Abstract】 The openness of wireless channel in sensor networks are vulnerable to jamming attack,wherein the reactive jamming attack with hidden high is the most difficult to be detected.This paper analyzes and summarizes the classical detection methods of interference attack in wireless sensor networks,and proposes a combination detection method of signal strength and retransmission rate.Experiments with CC2430 chip demonstrate that the detection scheme proposed in this paper can detect reactive jamming attack more accurately than signal strength consistency detection method.更多还原
