“…Moving networks, due to their highly volatile nature, experience significant quality issues since Vehicular Penetration Loss (VPL) can be observed due to the velocity of the vehicles and the attenuation of the radio signals that travel from the base station (BS) to the users devices, inside the vehicles or even to the vehicles themselves. This fact, inevitably, leads to increased interference and poor performance [25]. Moving devices may suffer from low signal quality caused by the poor macro antenna coverage of base stations inside vehicles with metallic walls.…”

“…Moving devices may suffer from low signal quality caused by the poor macro antenna coverage of base stations inside vehicles with metallic walls. According to [25], in such cases, the Vehicular Penetration Loss (VPL) can be as high as 25 dB in a minivan at the frequency of 2.4 GHz, with higher VPLs expected in higher frequency bands as well as in well insulated, metal high speed transportation means (trains, small airplanes etc). The problem is expected to intensify, when future mobile communication networks commence their operation in higher communication frequencies.…”

“…Therefore, advanced algorithms, sophisticated multiantenna solutions and more advanced signal processing techniques can be integrated into Mobile Relay Nodes (MRNs) to cancel interference [27]. According to [25] significant performance improvements were shown in both urban and rural scenarios, considering a ground moving vehicle. Furthermore, to meet the increasing bandwidth demands [25] proposes to adopt mm-wave technology in the Moving Networks, which will however exacerbate above stated losses.…”

Complex Systems: A Communication Networks Perspective Towards 6G

Over the last few years, the analysis and modeling of networks as well as the analysis and modeling of networked dynamical systems, has attracted considerable interdisciplinary interest, especially using the complex systems theory. These efforts are driven by the fact that systems, as diverse as genetic networks or the Internet can be effectively described as complex networks. Contrary, despite the unprecedented evolution of technology, basic issues and fundamental principles related to the structural and evolutionary properties of communication networks still remain largely unaddressed. The situation is even more complicated when we attempt to model the mobile communication networks and especially the 5th generation (5G) and eventually the forthcoming 6th generation (6G). In this work, we attempt to review basic models of complex networks from a communication networks perspective, focusing on their structural and evolutionary properties. Based on this review we aim to reveal the models of complex networks, that may apply when modeling the 5G and 6G mobile communication networks. Furthermore, we expect to encourage the collaboration between complex systems and networking theorists toward meeting the challenging demands of 5G networks and beyond.

“…The 60 GHz unlicensed band is largely uncongested compared to the 2.4 GHz and 5.8 GHz bands, and has not yet been investigated by 3GPP Release 16 to be supported by 5G New Radio-Unlicensed (NR-U), whose current target is to extend the applicability of 5G NR to sub 7 GHz unlicensed spectrum bands. So, we choose the 60 GHz band because of the ability to utilize a huge unlicensed bandwidth, so to provide multiple Gbps transmission rates [4]. However, because of the high frequency, 60 GHz transmissions are characterized by strong propagation loss.…”

In high-density indoor environments (e.g., airports or malls), it is expected an increase in data demand, in the number of applications having stringent Quality-of-Service requirements, and in the number of services among nearby users, such as video sharing or gaming. In order to satisfy these requirements, we adopt D2D communications, 60 GHz band transmissions, and adaptive beamforming techniques. The symbiosis of these technologies provides notable energy saving, high data rate, and strong interference reduction. Despite these benefits, a major issue is the limited communication range, due to the high path loss. To overcome this issue, we consider a Millimeter-Wave Mobile Broadband (MMB) system, consisting of several Access Points interconnected among themselves through a wireless backhaul network. Based on the specific features of the technologies adopted for the considered MMB system, we aim to improve the transmission efficiency, by exploiting concurrent transmissions. Therefore, we propose a new centralized access control scheme which jointly manages D2D communications and transmissions in the access and the backhaul network. Our control strategy aims to maximize the system throughput, to minimize the end-to-end delay, and to improve the fairness among users, while taking into account to keep the computational load as low as possible. To meet these goals, our proposed access control scheme is composed of a data flow management strategy and a multi-criteria scheduling algorithm based on greedy graph vertex-coloring techniques.

Among the emerging technologies for the fifth‐generation (5G) cellular networks, in‐band full‐duplex (FD) wireless communication and heterogeneous networks (HetNets) are two promising technologies, which can significantly improve the network capacity. Due to self‐interference (SI) and multiple sources of intercell interference, base station (BS)‐BS interference and user equipment (UE)‐UE interference in FD HetNets, interference management is a significant and challenging issue in such a network. To this end, in this article, we study the joint subchannel assignment and power control problem in the OFDMA FD HetNet. The joint subchannel assignment and power control problem in this network is formulated as an optimization problem to maximize the uplink and downlink sum throughput of the femtocell user equipments (FUEs) taking into account the maximum interference constraint imposed on the macrocell user equipments (MUEs) and the minimum throughput constraint of FUEs. Since the formulated problem is a nonconvex and intractable mixed integer nonlinear programming (MINLP) problem, we invoke variable change and linear approximation to reformulate and convert the problem into a tractable mixed‐integer linear programming (MILP) problem. Numerical results show that the optimal solution of the new MILP problem is very close to the optimal objective value of the original MINLP problem. The results also demonstrate that in an OFDMA FD HetNet, when all the UEs and the BSs are FD, approximately 50% improvement in the network throughputcan be achieved compared with a half‐duplex HetNet.
