Recently, sensor networks, cyber physics systems, and internet of things become popular because sensing, communication, and analytics technologies become more mature. In the future, digital sensing, communication, and processing capabilities will be ubiquitously embedded into everyday objects, turning them into an Internet of Things (IoT, also known as, machine-to-machine, M2M, 智慧聯網或物聯網). Sensors everywhere can continuously collect a large quantity of data; processors everywhere can analyze and infer useful knowledge from the data; communication ratios can transmit and exchange useful knowledge with other everyday objects to serve human better. This paradigm shift, while can significant improve our life, brings up numerous challenges and opportunities to engineering. This course aims to provide a timely discussion on the technical trends and challenges of Internet of Things.
