Abstract

To achieve fast and reliable transmission of underwater data, a new type of optical-acoustic hybrid underwater wireless sensor network (OA-UWSN) is proposed in this paper, and a new media access control (MAC) protocol with optical-acoustic (O-A) handshake is designed for the proposed network, in which the optical-acoustic request to send (RTS)/clear to send (CTS) message handshake is used to ensure the reliability of communication. The new protocol also adopts a time-slot reservation and back-off mechanism based on the optical-acoustic handshake. OMNET++ simulation software is used to simulate OA-UWSN and MAC protocols. The results show that the channel utilization of the proposed protocol in OA-UWSN is enhanced 24% more than T-Lohi protocol, and the OA-UWSN energy consumption of the proposed protocol is far lower than acoustic communication network.
