WSNs中采用动态模阈值检测DDoS攻击

摘要

无线传感器网络正逐渐过渡到实际的应用,在这些应用环境中,WSNs会遭到曾经危害过因特网和无线网络的攻击.DDoS攻击是这类攻击中的一种.这一恶意攻击甚至可以导致一些大型的网络拒绝合法顾客,合伙人和用户的服务.本文通过使用一种简单有效的方法来检测DDoS攻击.与以前提出的基于统计知识的统计阈值方法不同的,该方法的动态阈值基于模糊数学,是一种鲁棒性较强的方法.%Wireless sensor networks(WSNs)are transitioning to real world applications，where they will face attacks already experienced by the Internet and wireless networks.One of such attacks is Distributed Denial of Service(DDoS)attack.This kind of malicious attacks can even cause some biggest web sites on the world become deniable to legal customers，partners，and users.In this paper，we propose a simple and efficient method on the detection of DDoS attacks.Unlike previous proposals for static threshold that are based on statistical knowledge，the presented method is a robust method which has a dynamic threshold based on fuzzy mathematics.
