Simulation Research on Underwater Acoustic Network MAC Layer Protocol Attack

Because of the importance of underwater acoustic network MAC layer protocol, feasibility and simulation analysis of underwater acoustic network MAC layer protocol attack were carried out in this article. The principle of underwater acoustic network MAC layer protocol attack was introduced, simulation analysis of performance of attacking methods, including modification of backoff time and NAV values, was carried out, the simulation results showed that in special settings, MAC layer protocol attacking methods cause the network throughput degraded to less than 50% of the throughput level without attacking, in the same time, the network end to end delay came to about 200% level of the end to end delay without attacking.
