Low-Power IoT Networks for Space Applications

Abstract

The volume of traffic produced by Machine-type Communications (MTC) is increasing rapidly, exerting significant strain on current network infrastructures. One of the most formidable issues nowadays is facilitating machine-to-machine (M2M)/Internet of Things (IoT) data exchanges by ensuring connection between any two M2M devices globally. Consequently, this study examines the function of Space Information Networks (SINs) in facilitating MTC.             
This document examines horizontal solutions to facilitate interworking by serving as relay entities across various protocol stacks and services delivered vertically across distinct network segments. We examine the unresolved problems obstructing interworking and offer a potential protocol stack for M2M/IoT communications based on the oneM2M standard. This research ultimately evaluates the performance attainable via two widely used application protocols, Constrained Application Protocol (CoAP) and Message Queuing Telemetry Transport (MQTT), elucidating their efficiency and distinctions.
