Abstract
The SHETLAND-NET research project aims to build an Internet of Things (IoT) telemetry service in Antarctica to automatize the data collection of permafrost research studies on interconnecting remote wireless sensor networks (WSNs) through near vertical incidence skywave (NVIS) long fat networks (LFN). The proposed architecture presents some properties from challenging networks that require the use of delay tolerant networking (DTN) opportunistic techniques that send the collected data during the night as a bulk data transfer whenever a link comes available. This process might result in network congestion and packet loss. This is a complex architecture that demands a thorough assessment of the solution’s viability and an analysis of the transport protocols in order to find the option which best suits the use case to achieve superior trustworthiness in network congestion situations. A heterogeneous layer-based model is used to measure and improve the trustworthiness of the service. The scenario and different transport protocols are modeled to be compared, and the system’s trustworthiness is assessed through simulations.
Highlights
Research studies from multiple disciplines are carried out every year in Antarctica [1].Researchers are temporarily placed in Antarctic base stations, normally located in the peripheral areas of the continent
Our research project, the SHETLAND-NET, proposes the use of near vertical incidence skywave (NVIS) high-frequency (HF) radio links to provide low-consumption Antarctic communications, continuing previous research on ionospheric communications [2]. The ionosphere reflects this signal, providing a long backhaul link of a 250 km radius coverage area [3,4]. Networks using this type of links can be classified as long fat networks (LFNs), which are characterized by having long links with a bandwidth delay product (BDP) greater than 1 × 105 bits (12,500 bytes) [5], following
We focused on modern transport protocols that have been proven to perform well [45] and Transmission Control Protocol (TCP) CUBIC, which is the standard transport protocol in most operating systems nowadays
Summary
Research studies from multiple disciplines are carried out every year in Antarctica [1].Researchers are temporarily placed in Antarctic base stations, normally located in the peripheral areas of the continent. One of the main challenges in Antarctica is its lack of conventional telecommunication systems [1], which hinders the deployment of wireless sensor networks (WSNs) This fact reduces the possibilities of carrying out research studies (e.g., automation of data collection and remote bases interconnection). To overcome these difficulties, our research project, the SHETLAND-NET, proposes the use of near vertical incidence skywave (NVIS) high-frequency (HF) radio links to provide low-consumption Antarctic communications, continuing previous research on ionospheric communications [2]. Networks using this type of links can be classified as long fat networks (LFNs), which are characterized by having long links with a bandwidth delay product (BDP) greater than 1 × 105 bits (12,500 bytes) [5], following
