【摘要】 无线传感器网络只有有限的带宽、存储容量和计算能力,并且使用动态拓扑结构,这使它容易受到各种类型的攻击。虫洞攻击是无线传感器网络面临的众多攻击中的一种。本文研究了无线传感器网络中应对虫洞攻击的方法并提出了一种基于RTT机制的检测和预防技术,AOMDV路由协议也被引入到这种机制当中。NS2仿真实验的结果表明,这种方法比文献中的其他方法具有更高的效率。更多还原

【Abstract】 Wireless sensor networks have limited bandwidth, storage capacity and computing speed, and use dynamic topology, which makes them vulnerable to various types of attacks. Wormhole attack is one of the many attacks in wireless sensor networks. This paper studies the methods to deal with wormhole attacks in wireless sensor networks and proposes a detection and prevention technology based on RTT mechanism. AOMDV routing protocol is also introduced into this mechanism. The results of NS2 simulation experiments show that this method is more efficient than other methods in literature.更多还原
