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
more &raquo; ... 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. , 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.
