“…Moreover, Software Defined Networking (SDN)-based approach can be applied to manage the spectral opportunities dynamically based on the distributed inputs reported from heterogeneous nodes of 5G networks [16]. Besides the aforementioned coordination-based spectrum sharing solutions, another promising approach is Cognitive Radio (CR) technology, which aims to enhance spectrum utilization dynamically either with the opportunistic spectrum access, i.e., interweave or with spectrum sharing based on interference avoidance, i.e., underlay paradigms [12,13].…”

Full-Duplex (FD) wireless technology enables a radio to transmit and receive on the same frequency band at the same time, and it is considered to be one of the candidate technologies for the fifth generation (5G) of wireless communications due to its advantages including potential doubling of the capacity, reduced end-to-end and feedback delays, improved network secrecy and efficiency, and starting with a detailed overview of FD-enabled DSS, we provide a comprehensive survey of recent advances in this domain. We then highlight several potential techniques for enabling FD operation in DSS wireless systems. Subsequently, we propose a novel communication framework to enable CST in DSS systems by employing a power control-based SI mitigation scheme and carry out the throughput performance analysis of this proposed framework. Finally, we discuss some open research issues and future directions with the objective of stimulating future research efforts in the emerging FD-enabled DSS wireless systems.

“…In this case, SDWN controllers can take part as an enabling technology to perform centralized processing, becoming responsible for different wireless functions coordination [16,17]. For example, SDWN controllers can be reprogrammed to analyze, allocate, and redistribute radio resources, in addition to controlling the handover, interference, energy, and radio resource sharing [18]. Also, SDWN controllers can serve as a framework to design novel solutions, for example, based on artificial intelligence to predict user handover mobility in a more harmonized manner, avoiding the need of specialized protocols and network middle-boxes, such as IEEE 802.21 and LTE's Mobility Management Entity (MME).…”

The fifth generation (5G) cellular infrastructure is envisaged as a dense and heterogeneous deployment of small cells overlapping with existing macrocells in the Radio Access Network (RAN). Densification and heterogeneity, however, pose new challenges such as dealing with interference, accommodating massive signaling traffic, and managing increased energy consumption. Heterogeneous Cloud Radio Access Networks (H-CRAN) emerges as a candidate architecture for a sustainable deployment of 5G. In addition, the application of SDN concepts to wireless environments motivated recent research in the so-called Software-Defined Wireless Networking (SDWN). In this article, we discuss how SDWN can support the development of a flexible, programmable, and sustainable infrastructure for 5G. We also present a case study based on SDWN to perform frequency assignment, interference, and handover control in an H-CRAN environment. Results allow the establishment of a tradeoff between wireless communication capacity gains and signaling overhead added by the employment of SDWN concepts to H-CRAN.

“…Secinti et al (2018) proposed CP that communicated with the UAV DP using wireless connections because the use of wired connections between the SDN controller and mobile UAVs is not practically feasible Secinti et al (2018); Gupta et al (2016). In this sense, there are two wireless CP 1 (WCP) classes, i.e., direct Han et al (2016) and indirect Akhtar et al (2016). In the former, direct wireless connections are used between the controller and the underlying WDP.…”

Software-defined networking (SDN), which has been successfully deployed in the management of complex data centers, has recently been incorporated into a myriad of 5G networks to intelligently manage a wide range of heterogeneous wireless devices, software systems, and wireless access technologies. Thus, the SDN control plane needs to communicate wirelessly with the wireless data plane either directly or indirectly. The uncertainties in the wireless SDN control plane (WCP) make its design challenging. Both WCP schemes (direct WCP, D-WCP, and indirect WCP, I-WCP) have been incorporated into recent 5G networks; however, a discussion of their design principles and their design limitations is missing. This paper introduces an overview of the WCP design (I-WCP and D-WCP) and discusses its intricacies by reviewing its deployment in recent 5G networks. Furthermore, to facilitate synthesizing a robust WCP, this paper proposes a generic WCP framework using deep reinforcement learning (DRL) principles and presents a roadmap for future research.
