Internet 0 is a low-speed physical layer designed to route 'IP over anything.' It was developed at MIT's Center for Bits and Atoms by Neil Gershenfeld, Raffi Krikorian, and Danny Cohen. When it was invented, a number of other proposals were being labelled as "internet 2." The name was chosen to emphasize that this was designed to be a slow, but very inexpensive internetworking system, and forestall "high-performance" comparison questions such as "how fast is it?" Effectively, it would enable a platform for pervasive computing -- everything in a building could be on the same network to share data gathering and actuation. A light switch could turn on a light bulb by sending a packet to it, they can be linked together by the user. ==History== Internet 0 was originally a minor, expedient bit of engineering support for other MIT projects. It was intended to network buildings, improve efficiency, and gather data through the control of HVAC systems (heating, ventilation, and air conditioning). The protocol works pretty well in a wide variety of media. The wide utility and multiple media of the protocol interested network theorists. It awakened a burst of academic papers, and started some commercial interest. The simple, inexpensive implementation still appeals to hobbyists and students, where most of the new implementations were found as of 2011. Modern implementations are mostly software on small microcontrollers, usually with a transistor to transmit, and capacitors to isolate the transmitter and receiver. The connector literally becomes the major expense of the communication system. Such a simple, inexpensive system can be embedded into many devices to allow data retrieval or control via the Internet -- these small devices can be used to form an Internet of Things. The current largest deployment of Internet 0 was at the Venice Biennale Architecture Exhibition, in the year 2008, by a group led by the Institute of Advanced Architecture of Catalonia, directed by the architect Vicente Guallart. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Internet 0」の詳細全文を読む スポンサード リンク
