摘要
拒绝休眠攻击是一类致力于快速耗尽节点能量的特殊拒绝服务攻击,无线传感器网络如何防御恶意节点的低速率拒绝服务攻击,保障节点正常生命周期是一个重要的问题。IEEE 802.15.4作为目前无线传感器网络较常使用的一种MAC协议,存在着信标广播漏洞。本文首次提出了一种针对该漏洞的拒绝休眠攻击方法及其防御机制,并通过仿真实验验证了攻击的危害性和防御机制的有效性。
A sensor node's power supply is targeted in the denial-of-sleep attack. Attacks of this type can reduce sensor lifetime from years to days and can have a devastating impact on a sensor network. IEEE 802.15.4 is a kind of MAC protocol for wireless sensor networks, which exists beacon broadcast vulnerability. This paper goes on to introduce a suite of mechanisms designed to detect and mitigate the effects of denial-of-sleep attacks on sensor networks. Both the harmfulness of the attack and the effectiveness of the defense mechanism have been verified through the simulation platform.
