TCBWD: Topological comparison-based Byzantine wormhole detection for MANET

There are many forms of Byzantine attacks, including byzantine black hole attack, Byzantine flood rushing attack, and byzantine wormhole attack. Among all these attacks, Byzantine wormhole attack is considered one of the most complicated and severe attack in mobile ad hoc networks (MANET). In Byzantine wormhole attack, a compromised attacker actively participates in all network functions, and at the same time records packets at one location, tunnels them to another location, and then retransmits them there into the network. Most of the existing solutions targeting Byzantine wormhole attack rely on encryption and authentication which tries to detect packet dropping or modification. In this paper, we propose to detect some abnormal topological features introduced by Byzantine wormhole tunnel to detect Byzantine wormhole attack. Our scheme is easy to implement. The simulation results also show that our scheme can achieve both high Byzantine wormhole detection rate and detection accuracy.
