U-observation system for device sensing and operating in IOT platform Environment

IoT technology is a future internet infrastructure technology where physical things that exist in the real world and virtual things that exist in cyber environment are linked through the internet, that can provide various services through interlinking these physical and virtual spaces. This study will explore the technology trends in imprementing IoT devices such as core technologies device platform, weirless sensor object communication, and network technology, and the basic structure and operation process of smart IoT middleware system IoT-CAS(Internet of Things Devices-Context Awareness Service) designed in this study is suggested.
