Underwater Cross Layer Protocol Design for Data Link Layer: Stochastic Network Calculus

Nowadays, the research in underwater coral farming development is increasing due to the incremental demand for a source of medicines. The coral farms are located in the depth of the seabed and physically monitoring the coral farms is not an easy task in an underwater environment. At the same time, wired communication makes massive deployment and maintenance costs. The terrestrial wireless communication protocols in air and their approaches cannot be directly implemented in underwater communication scenarios as seawater is a highly saline medium. The protocol design in underwater acoustic communication for coral farms is a challenging research domain. This paper proposes the Scheduled Process Cross Layer Medium Access Control (SPCL-MAC) protocol design using stochastic network calculus. The fundamental idea of this protocol is to schedule the handshaking communication during the reserved process cycle and coordinate the process among the physical and network layer in underwater wireless communication. Performance analyses for frame delivery ratio, end-to-end delay, and energy consumption of both transmission and reception are carried out. The proposed mathematical models are also evaluated for its accuracy using discrete event simulation studies.
