“…Other commercial systems employ ALOHA-based protocols suitable for specific traffic patterns. A quantitative evaluation of traditional satellite Medium Access Control (MAC) protocols in DtS-IoT scenarios with LEO constellations is provided in [23].…”

“…As a result, specific CubeSat protocols to serve the specific characteristics of the IoT traffic has been studied in the literature. In [23], it has been identified that advanced techniques such dynamic channelling or precise channel estimation (employed for interference cancellation), require costly resources often not available in low-cost CubeSat deployments. Among the random access MAC protocols evaluated, only a few become near the region where DtS-IoT supported by CubeSats provides a scalable, energy-efficient, and non-complex channel access mechanism to the ground sensor nodes.…”

“…Given the few available applicability studies of LoRa technology over the satellite link, and the lack of performance evaluations of the LoRaWAN MAC protocols over DtS-IoT [41,23], it remains largely unknown if these protocols are suitable for the scenario of study. Moreover, the IoT standards did not consider any satellite segment in the overall architecture, nor satellite standards considered low-power devices on the ground segment.…”

“…However, the main novelty in DtS-IoT is the need to control the channel access among thousands of devices to satellites over hundreds of kilometers. The challenges in designing link layer MAC protocols in satellite IoT contexts are surveyed in [17] and [23]. In general, when energy efficiency is very important, TDMA is the well suited multiple channel access scheme.…”

“…On the other hand, in many IoT deployments featured by a very high numbers of devices, and a limited portion of them having data to send, a fixed-assignment multiple access scheme such as TDMA might be inefficient [17]. Nevertheless, contention-based protocols, when used in the DtS-IoT context, need to integrate mechanisms to manage the links power imbalances, the uneven link delays, and the lack of high quality channel estimations [23]. In the remaining part of this subsection, we review recent proposals of MAC layer protocols suitable for DtS-IoT architectures.…”

The Internet of Things (IoT) has drawn an enormous attention into the scientific community thanks to unimaginable before applications newly available in everyday life. The technological landscape behind the implied surge of automated interactions among humans and machines has been shaped by plugging into the Internet very low power devices that can perform monitoring and actuation operations through very cheap circuitry. The most challenging IoT scenarios include deployments of low power devices dispersed over wide geographical areas. In such scenarios, satellites will play a key role in bridging the gap towards a pervasive IoT able to easily handle disaster recovery scenarios (earthquakes, tsunamis, and flash floods, etc.), where the presence of a resilient backhauling communications infrastructure is crucial. In these scenarios, Direct-to-Satellite IoT (DtS-IoT) connectivity is preferred as no intermediate ground gateway is required, facilitating and speeding up the deployment of wide coverage IoT infrastructure. In this work, an in-depth yet thorough survey on the state-of-the-art of DtS-IoT is presented. The available physical layer techniques specifically designed for the IoT satellite link are described, and the suitability of both the current Medium Access Control protocol and the upper layer protocols to communicate over space links will be argued. We also discuss the design of the overall satellite LEO constellation and topology to be considered in DtS-IoT networks.

Space Information Network (SIN) is a multi-purpose heterogeneous network. Due to the large-scale of SIN, its secure and stable operation is vulnerable to various threats. Much of current threat analysis for SIN is based on the network function or architecture. However, this approach cannot clearly divide the relation between threats and secure communication measures for a highly integrated network. Furthermore, it will lead to overlapping in segregation of secure duties. This paper presents a comprehensive review of threats and corresponding solutions in SIN from the perspective of network security attributes. In order to make the analysis applicable to more scenarios, the following three most essential attributes, confidentiality, integrity and availability, are selected as the threatened objectives. At the same time, for cross-reference with the analysis based on network function or architecture, this paper relates network layers to network security attributes through secure communication mechanisms. Specifically, the confidentiality includes confidential information-exchange and Authentication and Key Agreement (AKA), the integrity includes information identification and information restoration, and the availability includes link establishment, routing mechanism, and mobility management. According to above framework, this paper provides a cross-layer perspective for analyzing threat and enhancing the security and stability of SIN. Finally, this paper concludes with a summary of challenges and future work in SIN.
