The increasing need for observation in seawater or ocean monitoring systems has ignited a considerable amount of interest and the necessity for enabling advancements in technology for underwater wireless tracking and underwater sensor networks for wireless communication. This type of communication can also play an important role in investigating ecological changes in the sea or ocean-like climate change, monitoring of biogeochemical, biological, and evolutionary changes. This can help in controlling and maintaining the production facilities of outer underwater grid blasting by deploying unmanned underwater vehicles (UUVs). Underwater tracking-based wireless networks can also help in maintaining communication between ships and divers, submarines, and between multiple divers. At present, the underwater acoustic communication system is unable to provide the data rate required to monitor and investigate the aquatic environment for various industrial applications like oil facilities or underwater grit blasting. To meet this challenge, an optical and magnetic tracking-based wireless communication system has been proposed as an effective alternative. Either optical or magnetic tracking-based wireless communication can be opted for according to the requirement of the potential application in sea or ocean. However, the hybrid version of optical and wireless tracking-based wireless communication can also be deployed to reduce the latency and improve the data rate for effective communication. It is concluded from the discussion that high data rate optical, magnetic or hybrid mode of wireless communication can be a feasible solution in applications like UUV-to-UUV and networks of aquatic sensors. The range of the proposed wireless communication can be extended using the concept of multihop.

“…A study dedicated to the analysis of the effects of congestion is presented in [47,48]. The authors propose the use of mediation analysis, a technique used in social sciences, to evaluate the effects of congestion (the mediator variable) in the relationship between a dependent variable (such as reachability or the packet delivery ratio on the application layer) and an independent variable (the forwarding probability, p f ).…”

This thesis addresses the problem of disseminating broadcast packets in a multi-hop wireless ad hoc network. Specifically, it focuses on broadcasting protocols in which nodes make probabilistic decisions to forward packets. In connected multi-hop ad hoc networks, this type of protocol produces a broadcasting process that saves energy and bandwidth while offering a natural rotation of the subset of forwarders over time, yet it entails minimum overhead.
