Abstract:

Different from the internet,IoT extendes the techniques and applications of internet.The IoT's connection object from man to man,be extended to man to machine and machine to machine.Based on the convergence of the sensor network,EPC system and ubiquitous network,the IoT provides a ubiquitous multi-information access methods.Based on the convergence of internet,telecommunications network,cable TV and various types of access networks,the IoT achieves ubiquitous data transfer.The functionality of the IoT is to provide ubiquitous service capabilities for different socio-professional.A core idea of IoT's technology roadmap is convergence,on the basis of internet,by learning and absorbing the research and application results of related discipline,formes a information services infrastructure platform that combines the physical space and virtual space and man and machine.A core idea of IoT's fundamental properties is ubiquitous,also known as the ubiquitous network,including ubiquitous interconnected,ubiquitous technical supported and ubiquitous application integrated.

Key words: Internet of things, sensor network, EPC system, intercross and combine, ubiquitous
