In the absence of traditional communication infrastructures, the choice of available technologies for building data collection and control systems in remote areas is very limited. This paper reviews and analyzes protocols and technologies for transferring Internet of Things (IoT) data and presents an architecture for a hybrid IoT-satellite network, which includes a long range (LoRa) low power wide area network (LPWAN) terrestrial network for data collection and an Iridium satellite system for backhaul connectivity. Simulation modelling, together with a specialized experimental stand, allowed us to study the applicability of different methods of information presentation for the case of transmitting IoT data over low-speed satellite communication channels. We proposed a data encoding and packaging scheme called GDEP (Gateway Data Encoding and Packaging). It is based on the combination of data format conversion at the connection points of a heterogeneous network and message packaging. GDEP enabled the reduction of the number of utilized Short Burst Data (SBD) containers and the overall transmitted data size by almost five times.

“…However a specific analysis targeting only the NB-IoT is necessary, due to the particular technical peculiarities of this technology. In the literature, some research works already exist, studying the coverage extension of NB-IoT through LEO satellite [14] [13]. Nevertheless, due to the recent development of the NB-IoT standard with improved capabilities and the new 3GPP agreements for the satellite link design in NTN 5G air interface, an updated and more detailed link budget analysis is of utmost importance.…”

Low-power wide-area networks (LPWAN) have been rapidly gaining ground in recent years, triggered by their capability to satisfy important market segments. Narrowband Internet of Things (NB-IoT) is one of the most appealing LPWAN technologies, foreseen to play an important role in the fifth generation mobile communication (5G) network. In order to guarantee a worldwide coverage to the low-cost devices distributed all over the globe, satellite connectivity is a key asset due to their large footprint on Earth, especially in remote areas where the investment towards a terrestrial infrastructure is not justified. However, such terrestrial networks aiming at deploying satellite systems either as an integrated part of it or a stand-alone solution, would require a careful and detailed analysis covering several aspects and all the layers of communication. In this paper, we demonstrate the link budgets of a satellite-based NB-IoT system under different parameters, providing some simulation results as a benchmark for further study. In addition, we analyze and discuss the impact that different power budgets would have in important features of the NB-IoT network, such as delay, capacity and device battery life.

“…While LEO satellites can solve to a certain extent the problem of GEO large delays in the communication link, they suffer from an increased Doppler shift. Moreover, in IoT applications LEO orbits are advantageous due to their smaller propagation signal loss, which for the low complexity and cheap IoT devices is crucial to close the link-budget, as shown in [13]- [15]. A survey on satellite-based wireless sensor networks, focusing on system architectures and scenarios can be found in [16].…”

Internet of things (IoT) over satellite is an attractive system architecture which has been proposed as a key-enabling technology, to extend the coverage in remote areas (e.g. desert, ocean, forest, etc), particularly where a terrestrial network is impossible or impractical to reach. One of the most promising technologies that fit the IoT vision of low-power, wide area networks (LPWAN) is the narrowband IoT (NB-IoT). While low earth orbit (LEO) satellites are favourable because of their lower round trip time (RTT) and lower propagation loss in the communication link, they come up with a significantly increased Doppler shift. In our NB-IoT over LEO satellite architecture, we identify the problem of high differential Doppler among channels of different users on Earth, which leads to the performance degradation of our system. In this paper, we propose a resource allocation approach in order to reduce the high values of differential Doppler under the maximum value supported by the standard itself.
