Welcome to the Internet of Things, a new department with the mission of presenting fresh ideas and applications from a practitioner point of view. We’re interested in showcasing articles about real, implemented Internet of Things (IoT) systems—not theoretical treatments or laboratory-based proofs of concept. There are all too many of the latter and not enough of the former. This is especially true with academic papers about potential applications that seem very distant from the realities of implementation. The articles we’re interested in featuring can take many different forms, but here are some examples: • Descriptions of deployed IoT systems, particularly in “surprising” application domains. • Reports from workshops, panel discussions, and practice-focused roundtables of professionals and researchers. • Surveys and reviews of tools for building IoT systems, including examples of deployed systems built using the tools. • Thoughtful discussions of societal, legal, and ethical issues surrounding the deployment of IoT applications. When building real systems, failure is inevitable. But we often learn more from these failures than from our successes. Therefore, we invite articles that share unsuccessful experiences or lessons learned from failed (or moderately successful) IoT system deployment. We realize that it might be difficult to expose failures to the public domain, but there are positive ways to do so.
