The development of hybrid satellite-terrestrial relay networks (HSTRNs) is one of the driving forces for revolutionizing satellite communications in the modern era. Although there are many unique features of conventional satellite networks, their evolution pace is much slower than the terrestrial wireless networks. As a result, it is becoming more important to use HSTRNs for the seamless integration of terrestrial cellular and satellite communications. With this intent, this paper provides a comprehensive performance evaluation of HSTRNs employing non-orthogonal multiple access technique. The terrestrial relay is considered to be wireless-powered and harvests energy from the radio signal of the satellite. For the sake of comparison, both amplify-and-forward (AF) and decode-and-forward (DF) relaying protocols are considered. Subsequently, the closed-form expressions of outage probabilities and ergodic capacities are derived for each relaying protocol. Extensive simulations are performed to verify the accuracy of the obtained closed-form expressions. The results provided in this work characterize the outage and capacity performance of such a HSTRN.

“…Cooperative terrestrial-satellite transmission aided by satellite link increases the bandwidth, which is further strengthened by the network coding [7][8][9]. The satellite is also be used as a backhaul with the advantage to offload base station [10]. Utilizing the multiple modes under optimized network codes provides quick recovery of the lost packet and higher capacity.…”

Cooperative communication supported by device to device (D2D)-LEO earthed satellite increases the performance of the resilient network and offloads base station. Additionally, network coding in a packet-based cooperative framework provides diversity and speedy recovery of lost packets. Cooperative communication advantages are subject to effective joint admission control strengthened by network coding for multiple interfaces. Joint admission control with network coding involves multiple constraints in terms of user selection, mode assignment, power allocation, and interface-based network codewords, which is challenging to solve collectively. Sub-problematization and its heuristic solution lead to a less complex solution. First, the adaptive terrestrial satellite power sentient network (ATSPSN) algorithm is proposed based on low complex convex linearization of mix integer non-linear problem (MINLP), NP-hard. ATSPSN provides optimum power allocation, mode assignment, and user selection based on joint channel conditions. Second, a multiple access network coding algorithm (MANC) is developed underlying the D2D-satellite network, which provides novel multiple interface random linear network codewords. At the end, the bi-directional matching algorithm aiming for joint admission control with network coding, named JAMANC-stream and JAMANC-batch communication, is proposed. JAMANC algorithm leads to a less complex solution and provides improved results in terms of capacity, power efficiency, and packet completion time. The theoretical lower and upper bounds are also derived for comparative study.

Recently, studies on integration of satellitebased communication with terrestrial next-generation cellular networks (5G) have emerged in academia, standardization bodies and industry due to extended coverage and service enrichment possibilities for Mobile Network Operators (MNOs). In this article, we (i) first review the existing studies on satellite-based mobile network architectures and standardization efforts, (ii) propose a new satellite-based backhaul architecture for mobile communications and evaluate comparative end-to-end performance of both proposed satellite based backhaul and pure terrestrial architecture deployment scenarios through realistic experimental evaluations in terms of various Key Performance Indicators (KPIs) used by MNOs (iii) discuss about encountered limitations and challenges well as the open issues of the experimented satellite-based mobile backhaul architecture (iv) and finally provide a reference architecture and some guidelines towards designing a satellite based backhaul for next generation cellular networks from the perspective of MNOs.
