摘　　要：在Sybil攻击下无线传感网络吞吐量会下降,因此,设计了基于MDP的无线传感网络Sybil攻击检测系统。分析无线传感网络Sybil攻击原理,以此设计系统硬件,包括无线传感模块、Sybil攻击嗅探器模块、攻击检测警报器模块。在系统硬件的支持下,构建基于MDP的攻击检测模型,即对网络节点的权值进行更新,计算不同节点间的信号传输强度值。依据信号传输强度确定节点位置,以此确定节点受到Sybil攻击情况,实现无线传感网络Sybil攻击检测。由实验结果可知,该系统在单、多Sybil节点攻击下,最大吞吐量分别为380 Mbps、248 Mbps,吞吐量保持在较高的水平,说明Sybil攻击检测效果好。The throughput of wireless sensor network will decrease under Sybil attack,so a wireless sensor network Sybil attack detection system based on MDP is designed.Analyze the Sybil attack principle of wireless sensor network,and then design the system hardware,including wireless sensor module,Sybil attack sniffer module,and attack detection alarm module.With the support of the system hardware,an attack detection model based on MDP is built,that is,the weight of the network node is updated,the signal transmission strength value between different nodes is calculated,and the node position is determined according to the signal transmission strength,so as to determine the status of the node being attacked by Sybil and realize the detection of the Sybil attack in the wireless sensor network.According to the experimental results,the maximum throughput of the system under single and multiple Sybil node attacks is 380 Mbps and 248 Mbps respectively,and the throughput remains at a high level,indicating that the Sybil attack detection effect is good.
