| Abstract: | IOT, IOT system and IOT event are the three levels of the concept of the Internet of Things. IOT application is realized in IOT systems. IOT has three layers： application layer, network layer and physical layer. Application layer shows the function and serv- ice requirement of IOT system; network layer is the network basis for IOT implementation; physical layer is the underlying environment for the interconnection and interaction of physical objects. IOT system basic characteristics include unattended operation, automation, intelligence, real-time characteristic and infinity. |
