... The study into NTN cooperation with the TN network progresses towards the definition of workable architecture between both. The prominent candidate of NTN technology is satellite technology, and multiple integration types are discussed in [11]. The 3GPP in Release 17 (R17) specified the enhanced functions for the foundational technologies that include coverage and capacity. ...

... This proposed algorithm could minimize respectively the average task latency and the average energy consumption of edge servers. In [58], an HAP collected and processed users' task data. Distinguishing from [57], the HAP could further offload the task data to multiple satellites simultaneously for edge computing. ...

... Microsensors with self-powered capabilities have substantial potential in Internet of Everything applications, as they are small and can operate independently without reliance on electrical grid supply, harvesting energy from the ambient environment instead [1][2][3][4]. By implementing solar cells using standard CMOS processes, the size of these sensors would be significantly reduced, as it integrates solar cells, energy harvesting systems, and sensor systems on a single chip, as shown in Fig. 1. ...

... Firstly, smart meters are lightweight terminal equipment [6]. Without hardware protection [7], an adversary may physically attack the smart meters to modify the electricity data or obtain the smart meters' private keys through a side-channel attack [8], thereby disguising it as a legitimate meter. Secondly, if the adversary can steal fine-grained data from smart meters, it could become a potential threat to the users' privacy. ...

... Fifth-Generation (5G) mobile cellular networks are evolving towards a ubiquitous platform that offers large-scale and distributed communication and computation capacities to support future Machine Learning (ML) and Artificial Intelligence (AI)-based services [1]. Integration of Smart Grid (SG) with 5G network will foster accelerated transition to a flexible, softwarized, data-driven and intelligent grid, recognised by the Third Generation Partnership Project (3GPP) work plan for Release 18 of 5G standards [2]. 5G networks provide necessary bandwidth, connection density, low latency and ultrareliability to support different SG services [3]. ...

... Release 18, which supports multi-RAT systems, was introduced to provide satellite and terrestrial RANs with their own dedicated radio resource management [23]. A 5G network slice instance is composed of a set of virtual network function (VNF) instances to form the end-to-end virtual network for the slice to operate independently [24]. In a Electronics 2024, 13, 4414 3 of 30 network slice instance, both terrestrial and non-terrestrial RANs can be created by the network operator [25]. ...
