Demo Abstract: Simulating Conflict Detection in Heterogeneous Services of a Smart City

Despite the increasing intelligence of smart services and sophistication of IoT platforms, the safety issues in smart cities are not addressed adequately, especially the safety issues arising from the integration of smart services. Therefore, in this demo abstract, we present CityGuard, a safety-aware watchdog architecture to detect conflicts among actions of heterogeneous services considering both safety and performance requirements. This demo simulates parts of New York City to depict how CityGuard identifies unsafe actions and thus helps to prevent the city from safety hazards, detects two major types of conflicts, i.e., device and environmental conflicts, and improves the overall city performance in terms of multiple performance metrics. This demo complements the full paper on CityGuard that appears in this conference.
