“…A similar approach was followed in [17], where the end-toend (E2E) packet delay is measured by varying the number of considered cubesats (i.e., 4 or 8). Regarding the RA procedure, the number of preambles is set to 48, the periodicity is fixed to 240 ms, and the BO parameter is 2048 ms, in order to mitigate the probability of collisions.…”

Through the transition from 5G to 6G, a significant rise in the number of Internet of Things (IoT) devices is anticipated, enabling pervasive and uninterrupted connectivity for several applications, in different verticals. Coping with the substantial influx of IoT devices and fulfilling the high capacity demands of different IoT technologies, such as NB-IoT, will necessitate the involvement of Non-Terrestrial Networks (NTNs), which will serve as crucial complements to terrestrial systems, enhancing the availability, resilience, and coverage of the network and will guarantee cost/benefit for some services and will fully satisfy some key requirements. Nevertheless, a primary obstacle to be faced when integrating IoT terrestrial communication systems in NTN, in particular with Non-Geostationary (NGSO) satellites, lies in the short visibility time of the flying platform due to its high speed. The latter introduces criticalities in various communication phases, including the Random Access (RA) procedure. In a highly congested scenario, the large Round Trip Delay and a limited visibility window, which varies for each user within the satellite's coverage area, contribute to reducing the number of users successfully concluding the RA procedure. In this paper, to enhance the percentage of users who successfully conclude the RA, we introduce the concept of Coverage Enhancement Levels in time and a novel backoff mechanism, namely Smart Backoff, that leverages the beam coverage visibility period of individual users to adjust the random backoff interval. The numerical results obtained from our proposed scheme substantiate significant improvements compared to the standard backoff scheme. Specifically, our approach yields an increase of up to 16% per channel in the percentage of users who successfully complete the RA process.

Satellite-terrestrial integrated networks have been proposed as a promising solution to provide global seamless coverage in next-generation communication networks. To enable the integration of satellite and terrestrial networks, network simulation is a fundamental and economically efficient step compared to the high cost of field trial and real-world system deployment. Simulation challenges arise with the fast growth of LEO mega-constellations, including frequent re-connection and handover, long satellite transmission delay, high dynamics of satellite network topologies, and the integration of heterogeneous infrastructures. More requirements emerge for satellite-terrestrial integrated simulation, including fidelity, scalability, extensibility, agility, and real-time. However, there is a lack of a state-of-the-art review for relevant simulators. To the best of our knowledge, this paper is the most comprehensive and latest survey that covers network simulators for satellite-terrestrial integrated networks, with all or partial simulation functionalities for satellite orbit simulation, physical layer modeling, and network protocols and algorithms. Compared with existing surveys, this survey contributes from three aspects: (1) an up-to-date collection and a comprehensive taxonomy of simulation tools in the past decade; (2) a summary of the main requirements and challenges; and (3) an inspiring summary for new research opportunities and publicly available simulation tools for follow-up research.

The adoption of the NB-IoT technology in satellite communications intends to boost Internet of Things services beyond the boundaries imposed by the current terrestrial infrastructures. Apart from link-level studies in the scientific literature and preliminary 3GPP technical reports, the overall debate is still open. To provide a further step forward in this direction, the work presented herein pursues a novel service-oriented methodology to design an effective solution, meticulously stitched around application requirements and technological constraints. To this end, it conducts link-level and system-level investigations to tune physical transmissions, satellite constellation, and protocol architecture, while ensuring the expected system behavior. To offer a real smart agriculture service operating in Europe, the resulting solution exploits 24 Low Earth Orbit satellites, grouped into 8 different orbits, moving at an altitude of 500 km. The configured protocol stack supports the transmission of tens of bytes generated at the application layer, by also counteracting the issues introduced by the satellite link. Since each satellite has the whole protocol stack on-board, terminals can transmit data without the need for the feeder link. This ensures communication latencies ranging from 16 minutes to 75 minutes, depending on the served number of terminals and the physical transmission settings. Moreover, the usage of the Early Data Transmission scheme reduces communication latencies up to 40%. These results pave the way towards the deployment of an effective proof-ofconcept, which drastically reduces the time-to-market imposed by the current state of the art.
