Adopting Stochastic Network Calculus as Mathematical Theory for Performance Analysis of Underwater Wireless Communication Networks

Underwater Wireless Communication Network (UWCN) is highly emerging in recent times due to the broad variety of underwater applications ranging from disaster prediction, environmental resource monitoring, military security surveillance and assisted navigation. Since the kind of accuracy these applications demands from the dynamic underwater environment is really high, so there is a need for effective way of study underwater communication networks. Usually underwater networks can be studied with the help of actual underwater testbed or with the model of the underwater network. Studying the underwater system with the actual underwater testbed is costly. The effective way of analysis can be done by creating a mathematical model of underwater systems. Queuing theory is one of the most popular mathematical theories used for conventional circuit switched networks whereas it can’t be applied for modeling modern packet switched networks which has high variability compared to that of circuit switched networks. So this paper presents Stochastic Network Calculus (SNC) as the mathematical theory for modeling underwater communication networks. Underlying principles and basic models provided by SNC for analyzing the performance graduates of UWCN is discussed in detail for the benefit of researchers looking for the effective mathematical theory for modeling the system in the domain of underwater communication.
