Integration of Cloud computing and body sensor networks

摘要

Wireless Sensor Networks (WSN) are revolutionizing distributed sensing in a wide range of application domains, ranging from home automation to process monitoring, healthcare analysis, weather forecasting, military situation awareness, and traffic control. Sensor nodes in a WSN can generate a large amount of real-time, in-situ contextual data about a specific monitored space, e.g. agricultural field, city quarter, building, room, human body. The capabilities of a WSN do not only involve collection and forwarding of raw sensor readings, but also include in-node/in-network data processing (e.g. aggregation and merging) and, sometimes, in-network complex elaboration, such as event detection, object tracking and classification based on even sophisticated distributed classification algorithms.
