Abstract

Antarctica is a key location for many research fields. The lack of telecommunication systems that interconnect remote base camps hardens the possibility of building synergies among different polar research studies. This paper defines a network architecture to deploy a group of interconnected remote Antarctic wireless sensor networks providing an IoT telemetry service. Long backhaul NVIS links were used to interconnect remote networks. This architecture presents some properties from challenging networks that require evaluating the viability of the solution. A heterogeneous layer-based model to measure and improve the trustworthiness of the service was defined and presented. The model was validated and the trustworthiness of the system was measured using the Riverbed Model simulator.

Highlights

During the last half-century, Antarctica has been a key location for many research studies in several fields such as oceanography, bioscience, geoscience, physical sciences, and other environmental studies [1]
We propose to classify them into the following four categories that will be used later to define our trustworthiness model: 1. Data Trustworthiness: It is defined as the possibility of ascertaining the correctness of the data provided by the source [33]
An N x M-dimension grid with all the possible combinations of stimulation parameters was formed, where M is the number of different Pb0 values, and N is the number of different Ground Terrestrial Network-Permafrost (GTN-packets sent (Ps)) node combinations per gateway (10 in standard mode and 100 in redundancy mode)

Summary

Introduction

During the last half-century, Antarctica has been a key location for many research studies in several fields such as oceanography, bioscience, geoscience, physical sciences, and other environmental studies [1]. Many bases have been settled in the peripheral areas of the Antarctic continent [2], the difficult environment and terrain provoke numerous challenges when it comes to implementing new operational services for modern studies. One of these challenges is the lack of telecommunication systems in Antarctica [3], especially wireless sensor networks (WSNs). Most Antarctic bases are not interconnected [3] This fact lowers the possibilities for different research groups to collaborate on similar studies, and the advantages of providing synoptic region-wide observations and building synergies are lost [3].
