[...] * The rapid development of the Internet and web technologies allows ordinary users to generate vast amounts of data about their daily lives. On the Internet of Things (IoT), the number of connected devices has grown exponentially; each of these produces real-time or near real-time streaming data about our physical world. In the IoT paradigm, an enormous amount of networking sensors are embedded into various devices and machines in the real world. Such sensors deployed in different fields may collect various kinds of data, such as environmental data, geographical data, astronomical data, and logistic data. Mobile equipment, transportation facilities, public facilities, and home appliances could all be data acquisition equipment in IoT.
