Abstract
In this work, the development of a software-in-loop platform to carry out Underwater Wireless Sensor Network (UWSN) simulations using a real-time STANAG 5066 stack is presented. The used protocol stack is part of a real-world implementation of an underwater wireless node based on ElectroMagnetic (EM) Underwater Radio Frequency Communication (EM-URFC), framed within Spanish Government’s project HERAKLES. The main objective of this work was to assess the suitability of this software-in-loop approach for carrying out realistic UWSN simulations. In addition to a detailed description of the simulation process, several simulations considering an illustrative network topology are performed, analyzing the impact of different critical parameters on the network performance. The conclusions suggest that the developed software-in-loop platform is suitable to carry out UWSN network tests using a real-world implementation of the STANAG 5066 stack. Moreover, other real-time protocol stacks may be easily adapted with minor modifications.
Highlights
Underwater Wireless Sensor Networks (UWSN) is an important research field devoted to providing scalable and flexible platforms for a wide range of underwater applications
This paper focuses on the development of a software-in-loop platform capable of simulating the behavior of an underwater network of Multiple Input Node Interface for Offshore Networking (MINION), which uses a real-implementation of the STANAG 5066 stack
The software-in-loop platform was running simulations for several days in order to extract the results presented
Summary
Underwater Wireless Sensor Networks (UWSN) is an important research field devoted to providing scalable and flexible platforms for a wide range of underwater applications. Some of these applications are related to oceanic monitoring, underwater positioning, and Autonomous. There are three main technologies capable of operating in underwater environments: Underwater Acoustic Communication (UAC), Underwater Wireless. Optical Communication (UWOC), and Underwater Radio Frequency Communication (URFC). Underwater wireless communication has been carried out using pressure waves. The underwater acoustic channel suffers from saturation, a significant human-generated noise background level, and the possibility of harming cetaceans if the used carrier frequencies are below 200–300 KHz [3]
