This three-year Project Grant from the National Science Foundation's $398,719 Computer and Information Science and Engineering program will fund research into a new "Internet of Collaborating Things" architecture approach. The University of Massachusetts will develop foundations for a massive-scale Internet of Things infrastructure without the large cost and energy footprint of traditional server models. Researchers will address secure multitenancy, collaboration, and resilient management of distributed resources across interconnected devices and physical environments. They will release open-source software, create experimental testbeds, and conduct outreach to advance education and broaden computing participation through local high school programs. This award supports the NSF's mission to advance computing and information science through investigator-initiated research and cyberinfrastructure development.
