摘　　要：由于无线链路的开放性,节点生存周期有限,网络拓扑结构动态变化,传统的基于防火墙的安全策略作用有限,使得无线传感器网络(WSNs)存在严重的安全性问题。入侵检测系统IDS(Intrusion Detection System)作为一种主动防御方式,成为了当前研究的热点问题之一。论文针对目前IDS发展现状,采用基于博弈论的分析方法,建立可应对多目标、多攻击源和多攻击强度的IDS模型,使在对攻击的防御成功率和延长网络生存周期上都有所改进。Security is one of the most important issues of wireless sensor networks (WSNs), because of the open-access of wireless link, the limited survival circle, dynamic topology changing. The traditional security strategy based on firewall takes a little of effects .The IDS that acts as an initiative defending method, has become a hot approach to security. This paper analyzes the current status of IDS, builds a model that could handle the multi-object、multi-attacker、multi-level attack, improves the probability of succeeding in defending attack, extends the whole networks survival cycle.
