水下传感器网络的虫洞攻击模拟

Modeling wormhole attack in underwater sensor network

在水下传感网络中,为了提供可靠的通信,安全成为一个首要关注的问题。通过分析目前模拟虫洞攻击的方法后,提出一个在NS2中用于水下传感器网络的虫洞攻击模拟方法。虫洞攻击的核心在于在两个恶意节点之间建立"隧道"。如果在两个恶意节点之间形成了"隧道",那么正常节点就会丢失路由。为了解决这个问题,在NS2有线模拟包中选择了有线对象链接,通过复制本地包,并将其发送到远程节点的虫洞对象的方法来模拟"隧道"。实验结果表明,NS2中的虫洞组件运行有效,并且符合理论分析。

In underwater sensor network, security becomes a primary concern in order to provide protected communication. A novel network simulation component is proposed, in NS2, for underwater sensor networks, after analyzing the current methods of simulating wormhole attack. The core idea of wormhole implementation is making a ＂ tunnel＂ between two malicious nodes. If this ＂ tunnel＂ is built on normal wireless or wired channel, there would be some unexpected channel loss. So in order to solve the problem, the existing wired object Link is selected, in the NS2 wired simulation package, to simulate the ＂tunnel＂ by copy- ing the local packets and directly sending them to the wormhole object installed in a remote node. Experimental results demon- strate the effectiveness of the wormhole components in NS2 worked smoothly and comply with the actual.
