Untethered clouds

Welcome to this first issue on Industry Perspectives, a section dedicated to broad impact articles that aim to bridge the gap between academic research and emerging industry applications. In this issue, we showcase two articles. The usefulness of cloud computing as a virtualized Internet resource has been well documented. The first article by Jan Kruys describes how wireless technologies such as WiFi, WiMax/LTE, and Wi-Fibre can expand the reach of this resource, and enable pervasive on demand computing. The second article by Nada Golmie focuses on the key functionalities for achieving seamless mobility in wireless networks, and explains why deployment challenges remain even though standards and solutions are available. I hope these articles help shed some light on real-world problems that may, in turn, spawn new research topics. I take this opportunity to thank the authors for their fine efforts and to invite potential contributors for future sections.
