Cooperative Resource Management for Cognitive Satellite-Aerial-Terrestrial Integrated Networks Towards IoT

Abstract

With the ubiquitous deployment of Internet-of-Things (IoT) devices and applications, satelliteaerial-terrestrial integrated network (SATIN) is regarded as a promising candidate to facilitate global IoT with diverse services. To accommodate the explosive demands of IoT within crowded spectrum, we focus on the cognitive radio based SATINs where spectrum sharing is enabled among satellite, aerial, and terrestrial network segments, and devote to efficient resource management. Specifically, by reviewing main challenges that the characteristics of cognitive SATINs and the requirements of IoT bring to resource management, we analyze the potential of incorporating cooperation into cognitive SATINs for future intelligent IoT. Then, we propose a cooperative beamforming scheme to facilitate secure and energy-efficient IoT communications under limited energy for open channel environments in cognitive SATINs. Simulation results validate the superiority of cooperation resource management in cognitive SATINs towards IoT.

Hybrid Satellite–Terrestrial Networks toward 6G: Key Technologies and Open Issues

“…The authors of [ 147 ] introduced a cost-effective, flexible, and high-throughput architecture of a cognitive satellite–air–terrestrial integrated network (SATIN) for IoT. Proposing a cooperative beamforming scheme to enhance the security and energy efficiency of IoT communications in cognitive SATINs, the main challenges to efficient resource management in terms of 3D spatial–temporal deployment of UAVs, interference management, and physical layer security were analyzed.…”

5G Embraces Satellites for 6G Ubiquitous IoT: Basic Models for Integrated Satellite Terrestrial Networks

“…To explore the mmWave band in HSTNs, Zhang et al optimized the downlink beamforming of TBSs with the interference probability constraint of satellite users [101]. Ruan et al considered a scenario where the UAV acts as a malicious eavesdropper [102]. More recently, Liu et al investigated downlink beamforming with a nonlinear power amplifier [103].…”

HST-NNC: A Novel Hybrid Satellite-Terrestrial Communication With NOMA and Network Coding Systems

“…Moreover, [14] has proposed a relay selection scheme in an HSTN and conducted outage and throughput analysis, considering the effects of hardware impairments and interference on the multi-antenna terrestrial relays and the single-antenna terrestrial user. In another approach, [15] has studied cooperative resource management in spectrum sharing satellite-aerial-terrestrial integrated networks (SATIN), for energy-efficient IoT communications under energy constraints. Meanwhile, as compared to other higher orbit satellite-based architectures and within the context of HSTNs, LEO satellites have been proposed as a viable means for improving connec-tivity and data offloading with reduced latency [16], [17].…”
