Internetworking framework in underwater wireless sensor network protocol to a certain connectivity using probabilistic approaches

Ocean acidification is one of the parameters that affect underwater wireless sensor network routing protocols. The underlying network-level metrics of sensor nodes correspond to depth-dependent interactions. The spatial relevancy of sensor nodes varies drastically due to the mobility of the ocean column. In this work, complexity of the underwater environment and its characteristics are fed along with the sensor node capabilities of internetworking and its communication void. The wireless sensor node embeds medium access control layer timing of sensor packet transmission associated with its communication range and underwater characteristics of transmission and absorption losses. Underwater routing protocol for void avoidance transmission probability (UWRPVA-TP) is proposed, and sensors are deployed across diverse depths. Multi-hop communications as a function of depth-dependent attenuation across the ocean columns and their transmission probabilities have been calculated under mobility scenarios. The simulation result of UWRPVA-TP has been validated for the protocol using different attenuation models for energy consumption and number of alive nodes. Finally, the packet reliability ratio and deadline miss ratio has been calculated to understand the application of the time complexity associated with packet transfer.
