A New Technique for Underwater Acoustic Wireless Sensor Network

Medium Access Control (MAC) protocols play an important role in underwater environment communication. There is a strong need to enhance the performance of MAC protocols in Underwater Sensor Networks (UWSNs) especially improving the adequacy of ALOHA Protocols. In this paper, a Slotted-Buffering-ALOHA protocol is proposed. This protocol is based on three components: buffering, slot time, and Carrier Sense (CS). The simulation results demonstrated a superior execution of this protocol in the throughput rate, the energy consumption, and the average delay in comparison with the three protocols: slotted ALOHA, Slotted-CS ALOHA, and ST-Slotted-CS-ALOHA protocols.
