Editorial:

While the past few decades have witnessed the rapid growth in mobile and wireless networks, numerous problems and challenges become increasingly serious, such as heterogeneous wireless networks, spectrum scarcity, smooth evolving and fast deployment, technologies innovations, QoS and

QoE support, etc. Traditional mobile and wireless network technologies can hardly overcome these challenges.

Software defined network, an innovative paradigm, has become one of the hottest topics in wired and wireless networking. It advocates separating the control plane and data plane, and abstracting the control functions of the network into a logically centralized control plane. However, key technologies in software defined wireless networks (SDWN) are still open, including the end-to-end architecture, design and implementation of wireless technologies, software defining strategies, etc. At the same time, cloud computing and network virtualization are considered as a promising way that benefits future wireless networks, such as using the cloud computing pool providing powerful computing capability to implement the baseband data processing of wireless communication. However, how to design, customize, and utilize the virtualization and cloud computing technologies targeted for the wireless networks are still open problems.

The special issue focuses on the architecture and key technologies of software-defined and virtualized future mobile and wireless networks. We have received 40+ submissions, and finally accepted 8 papers to publish in this SI. At the same time, we have also selected 4 high quality best papers from

International Conference on Software-Defined and

Virtualized Future Wireless Networks, which held in

Rome, Italy, October 27, 2014. All these papers together investigated and discussed the following five major topics: network architectures for SDWN and virtualization, SDN wireless backhaul and IP network, resource allocations for SDWN, applications of SDWN, and corresponding security and charging problems.

For the network architectures of SDWN and virtualization, the first article, BSoftware-Defined and Virtualized Future

Mobile and Wireless Networks: A Survey ,^ co-authored by

Mao Yang, Yong Li, Depeng Jin, Lieguang Zeng, XinWu and

Athanasios V. Vasilakos, discusses the challenges and expectations of current wireless networks, and analyzed the opportunities provided by the SDWN and wireless network virtualization (WNV). Then, this paper focuses on SDWN and WNV by presenting the main ideas, advantages, ongoing researches and key technologies, and open issues respectively.

Furthermore, this paper interprets these two technologies highly complement each other, and investigates efficient joint design between them. This work confirms that SDWN and

WNV may efficiently address the crucial challenges and significantly benefit the future mobile and wireless network.

Access Networks^, co-authored by Heming Wen, Prabhat

Kumar Tiwary and Tho Le-Ngoc, presents Aurora, a virtualization framework and testbed platform for supporting multiple types of virtualization techniques and architectures specifically applied to wireless technologies. Aurora is designed to fulfill multiple roles as a powerful tool to combine multiple wireless virtualization technologies, a softwaredefined research platform for developing new virtualization architectures and a service-oriented wireless infrastructure manager.

For the topic of SDN wireless backhaul and IP network, article, BIntegrating WMN based mobile backhaul with SDN control^, co-authored by Kari Seppanen, Tapio Suihko and

Jorma Kilpi, provides solution of suitable backhaul connections for future broadband mobile networks by SDN-based wireless mesh networks (WMNs). This solution benefits the centralized controlling of SDN, and it is best suited in cases where base stations are installed in locations without optical fiber connection to transport network, e.g., small-cell deployment to hot spots in dense urban areas. On the other hand, article, BDesign and Implementation of A Software-defined

Mobility Architecture for IP Networks^, co-authored by You

Wang, Jun Bi and Keyao Zhang, applys the Software Defined

Networking (SDN) to mobile and wireless networking to make them adapt to the rapid development and popularity of the mobile Internet. It focuses on extending SDN paradigm to mobility handling in the mobile Internet by designing and implementing and deployment of a software-defined IP mobility architecture.

For the topic of resource allocations for SDWN, the article,

BConverged management in heterogeneous wireless networks based on resource virtualization^ co-authored by Luhan

Wang, Zhaoming Lu, Xiangming Wen and Wanqing Guan, focuses on the resource management in Dense heterogeneous networks (HetNets), which are supposed to be one of the most inevitable modalities of future radio access networks (RAN).

This paper proposes a converged management architecture for

HetNets (CMA) based on resource virtualization, which whittles traditional HetNets management down to the procedure of virtual resources allocation by demonstrating some use cases.

The article, BTraffic Aware Cross-Site VirtualMachineMigration in Future Mobile Cloud Computing^, co-authored by

Jiaqiang Liu, Yong Li, Depeng Jin, Li Su and Lieguang Zeng, focuses on the scenarios of mobile cloud computing, which is a new paradigm to provide Internet services to mobile users.
