Modeling the Wormhole Attack in Underwater Sensor Network

In underwater sensor network, security becomes a primary concern in order to provide protected communication. In this paper, we present a novel network simulation component, wormhole attack, 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, we selected the existing wired object Link, in the NS2 wired simulation package, to simulate the "tunnel" by copying the local packets and directly sending them to the wormhole object installed in a remote node. Experimental results demonstrate the effectiveness of the wormhole components in NS2 worked smoothly and comply with the actual.
