A Comparison of Two Secure Routing Protocols in Underwater Acoustic Network

There is an increasing requirement of the application of Underwater Acoustic Network (UAN) both in many fields. In the commercial applications, terrorists may carry through destroy activities; while in the military applications, even it is an inevitable activity to degrade the adversary UAN. Thus it can be seen that security measures must be integrated into UAN. This paper tries to do some efforts in the security of UAN, presenting two secure routing protocols. Comparisons are performed via simulation. Selected features include throughput, average bit error rate, and average end to end time delay, etc.
