Guest Editorial: Architecture for Next Generation Wireless Networks: Scalability, Flexibility, and Interoperability

The articles in this special issue focus on next generation wireless networks. Over the past decade, we have witnessed tremendous growth in the number of networked wireless devices, in the types of wireless and mobile applications, and in the total amount of traffic from and toward these devices. It is clear that future wireless networks have to accommodate even more devices, to facilitate diverse applications in these devices, and to exchange huge amounts of data for these applications. To tackle the challenges in the design of future wireless networks, we have organized this special issue focusing on the scalability, flexibility, and interoperability of future wireless networks.
