The ACM/IEEE International Conference on Internet of Things Design and Implementation (IoTDI) is a premier venue on IoT. In 2022, IoTDI will be held for the seventh time, co-located as part of CPS-IoT Week, the premier event on Cyber-Physical Systems and Internet-of-Things Research. A confluence of technological advances marks the advent of a new era. World data volume is growing at an unprecedented pace, much of it from embedded devices. AI/ML technology promise unprecendented levels of automation in system operation and data processing. Smart cities grow, fed by millions of data points from multitudes of human and physical sources, together with machine intelligence algorithms that extract value for applications. Cyber-attacks grow more nefarious, bringing down physical systems. Social media are becoming ubiquitous, offering additional information on physical things. The separation between cyber, physical, and social systems is blurring. Collectively, these developments lead to the emergence of a new multi-disciplinary field, where the networking and physical realms meet, often in social spaces. It is the field of the Internet of Things (IoT). This conference is an interdisciplinary forum that brings together researchers and practitioners from academia, industry and government to discuss challenges, technologies, and emerging directions in IoT system design and implementation. This conference invites original, previously unpublished work on a range of IoT topics, broadly defined.
