Guest Editorial Special Issue on Large-Scale Internet of Things

Internet of Things (IoT), as an ecosystem that interconnects physical objects with telecommunication networks, introduces a tighter connection between cyber space and physical reality. It has been widely recognized that our daily lives will be fundamentally improved with various IoT applications in environmental surveillance, healthcare, agriculture, public security, supply chain management, etc. Building on these successes and recent advances in information and communication technologies, IoT will develop toward largescale and ubiquitous directions, imposing increasingly higher requirements on safety, reliability, security, energy efficiency, performance, robustness, and cost efficiency. This introduces many unprecedented challenging issues across the disciplines of embedded system, manufacturing, telecommunication, computing, sensing, software engineering, data management, and analysis. Emerging and advanced communication technologies introduce many new opportunities to tackle the challenging issues in large-scale ubiquitous IoT.
