摘　　要：拒绝服务(DoS)攻击是一种主要的网络攻击方式,严重影响了无线传感器网络(WSNs)的正常运行。对WSNs中DoS攻击进行分析后,结合生物免疫原理,提出了一种基于免疫原理的DoS攻击检测算法。建立入侵特征库,使安全系统具有记忆和学习能力,大大减轻了重复检测所需的能量的消耗和资源的占用。粗糙集的使用解决了传感器网络中信息的不确定性和不完整性。仿真结果表明:提出的检测算法是可行、高效的,能够检测出各种DoS攻击。Denial-of-service（DoS） is a major attacking method in networks,which seriously influences normal operation of wireless sensor networks（WSNs）.DoS attack in WSNs is analyzed,a detecting algorithm against DoS attack based on immune principle is proposed.Intrusion characteristic library is established,so that security system is provided with learning and memorizing abilities.Energy consumption and resource occupation in repeated test is reduced greatly.Uncertainty and imperfection of information are solved using rough set in WSNs.Simulation results show that the proposed detecting algorithm is feasible,high efficient and can detect various DoS attack.
