CAMA-UAN: A Context-Aware MAC Scheme to the Underwater Acoustic Sensor Networks for the Improved CACA-UAN

Acoustic Communication is one of the most common and popular techniques used for Underwater Sensor Networks. The design of its communication protocol becomes a challenge due to its features of high delay and low bandwidth. Relevant research work has been conducted on possible communication at the MAC layer for highly efficient allocation and utility of communication channels. In this paper, a communication solution is designed called Context-Aware Mac-layer Approach to Underwater Acoustic Networks (CAMA-UAN), where a competitive mechanism is presented to determine the structure of scheduled MAC frames. According to the results, the CAMA-UAN has shown performance on delay and dropped packet ratio (DPR) when the rearrangement of frame slots is performed.
