An architecture for software defined wireless networking

by Carlos J. Bernardos, Antonio De La Oliva, Pablo Serrano, Albert Banchs, Luis M. Contreras, Hao Jin, Juan Carlos Zúñiga - Wireless Communications, IEEE , 2014
"... Abstract — Software Defined Networking (SDN), characterized by a clear separation of the control and data planes, is being adopted as a novel paradigm for wired networking. With SDN, network operators can run their infrastructure more efficiently, supporting a faster deployment of new services while ..."

1 Software-Defined Wireless Transport Networks for Flexible Mobile Backhaul in 5G Systems

by Dudu Bercovich Ceragon, Luis M. Contreras, Ariel Adam Ceragon
"... 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 t ..."

1Using Wireless Network Coding to Replace a Wired with Wireless Backhaul

by Henning Thomsen, Elisabeth De Carvalho, Petar Popovski
"... Cellular networks are evolving towards dense deployment of small cells, which requires flexible and efficient backhauling solutions. A viable solution that reuses the same spectrum is wireless backhaul where the Small Base Station (SBS) acts as a relay. In this paper we consider a reference system t ..."

of an Open Access and Back-haul Network Architecture for Small Cells based on Cloud Net-works) project with the objective of jointly optimizing backhaul and radio access network operations through the adoption of SDN (Software Defined Networking). Furthermore, based on this framework, the implementation

Testbed Innovations for Experimenting with Wired and Wireless Software Defined Networks

by Kostas Choumas, Nikos Makris, Thanasis Korakis, Ros Tassiulas, Max Ott - In CNERT workshop of IEEE ICDCS , 2015
"... Abstract—Widely available and remotely accessible testbeds have been used for a direct comparison of innovative protocols and ideas with existing technologies. Therefore, multiple testbeds have been established, aiming at providing experimentation services with both wireless and wired networks. In t ..."

attempts have been made towards bridging this gap in order to allow experimentation with heterogeneous wired and wireless resources. In this article, we present our contributions in extending the state-of-the-art control and management framework for wireless testbeds with support for Software Defined

An Architecture for Software Defined Cognitive Radio

by Aveek Dutta, Dola Saha, Dirk Grunwald, Douglas Sicker
"... As we move forward towards the next generation of wireless pro-tocols, the push for a better radio physical layer is ever increasing. Conventional radio architectures are limited to narrow operating regions and fails to adapt with changing technology. This is fur-ther strengthened with the advent of ..."

Trustworthy Foundation for CAVs in an Uncertain World: From Wireless Networking, Sensing, and Control to Software-Defined Infrastructure

by Hongwei Zhang, Le Yi Wang, George Yin, Shengbo Eben Li, Keqiang Li, Jing Hua, Yeuhua Wang, Chuan Li, Hai Jin
"... Three basic enablers for connected and automated vehicles (CAVs) are wireless networking, sensing, and control. Tightly coupled with the physical process of wireless signal propagation, vehicle movement, and environment, however, CAV wireless networking, sensing, and control are subject to complex c ..."
