无线传感器网络的拒绝服务攻击

在无线传感器网络的应用中,维护网络的可用性是尤为重要的。拒绝服务的攻击(Denial-of-service,DoS) 就是要降低甚至摧毁整个网络的功能,让网络彻底不可用。鉴于传感器节点自身资源的限制,必须要采取一些恰当的安全机制来预防拒绝服务的攻击。文章从传感器网络各层所遭受的各种常见的拒绝服务攻击出发,探讨传感器节点应对DoS 攻击的策略与方法。

The Denial-of-Service Attacks in Wireless Sensor Network

In the application of wireless sensor network, keeping the network available for its intended use is essential. The denial-of-service attack is referred to an adversary's attempt to dimmish or eliminate a network's capacity to perform its expected function. Due to the sensor node's constraints in its resources, we must adopt some appropriate security mechanisms to defend such attack. Each layer of the network is vulnerable to different DoS attacks and has different options available for its defense.
