“…SDMN can be used for introducing innovative services including improved monitoring and management of network resources. The "Connectivity management for eneRgy Optimized Wireless Dense networks" (CROWD) project [110] claims that SDN for mobile networks is an effective solution for MAC layer reconfiguration, dynamic backhaul reconfiguration, and connectivity management in dense and heterogeneous wireless networks [111]. These recent works that target RAN with RRHs (SoftRAN, CROWD) would also benefit operators in the deployment of C-RAN.…”

Abstract-Cloud Radio Access Network (C-RAN) is a novel mobile network architecture which can address a number of challenges the operators face while trying to support growing end-user's needs. The main idea behind C-RAN is to pool the Baseband Units (BBUs) from multiple base stations into centralized BBU Pool for statistical multiplexing gain, while shifting the burden to the high-speed wireline transmission of In-phase and Quadrature (IQ) data. C-RAN enables energy efficient network operation and possible cost savings on baseband resources. Furthermore, it improves network capacity by performing load balancing and cooperative processing of signals originating from several base stations. This article surveys the state-of-the-art literature on C-RAN. It can serve as a starting point for anyone willing to understand C-RAN architecture and advance the research on C-RAN.

“…The EU CROWD FP7 project proposed in [20], a comprehensive architecture based on SDN for cellular and WLAN technologies. The control plane is hierarchically organized into two tiers where "districts" have a local knowledge for short time scale decision and "region" have global information for more coarse grain long time scales In addition two North Bound APIs type are proposed namely: Technology Specific where optimization is performed on details specific to a given technology (e.g., InterFrame Space for WiFi AP) and Technology Agnostic which enable generic optimization on broad range of technology based on set of abstracted primitives.…”

Traditionally microwave backhaul has been configured and operated in a static manner by means of vendor specific management systems. This mode of operation will be difficult to adapt to the new challenges originated by 5G networks. New mechanisms for adaptation and flexibility are required also in this network segment. The usage of a signaled control plane solution (based on OpenFlow) will facilitate the operation and will provide means for automation of actions on the wireless transport network segment. In addition to that, a standard control plane helps to reach the multi-vendor approach reducing complexity and variety of current per-vendor operation. This paper presents the motivation for the introduction of programmability concepts in wireless transport networks and illustrate the applicability of such control plane with two relevant use cases for dynamically controlling wireless transport nodes in 5G networks. Extensions to OpenFlow protocol are also presented for building Software Defined Wireless Transport Networks (SDWTNs).

“…The Network Architecture based on SDN Taking CROWD project as an example [9], 802.11ac network resources, including the air-interface resources and backhaul resources, form a resource pool which can be centrally managed and dynamically allocated by SDN controllers. The SDN controllers are able to obtain real-time network information.…”

Abstract. The paper proposes network architecture based on software-defined networking (SDN), wireless network virtualization, the enhanced authentication and the fast handoff to achieve scalability, interference immunity and security, aiming to reduce adverse effects of the dense deployment on the performance of very high throughput (VHT) Wi-Fi. The experimental results show that the combination of SDN, network function virtualization, Galois/counter mode protocol and VHT Wi-Fi can improve throughput by 10%, which is able to maintain security while reducing the handoff delay to 40ms. The techniques mentioned above can guarantee the role of the VHT Wi-Fi in future dense deployment wireless networks.
