Study on the design of intelligent gateway of the Internet of things
ABSTRACT：Internet of Things are defined as follows:
Internet of Things:In a broad perspective,the IoT can be perceived as a vision with technological and societal implications.From the perspective of technical standardization,IoT can be viewed as a global infrastructure for the information society,enabling and advanced services by interconnecting(physical and virtual)things based on,existing and evolving,interoperable information and communication technologies.Though the exploitation of identification,data capture,processing and communication capabilities,the IoT makes full use of things to offer services to all kinds of applications,whilst maintaining the required privacy.
This article first introduces lightweight protocols and embedded operating system，Z-Stack，the establishment of a standardized，open network server architecture，its architectural style is based on the most basic of network protocol has able to send short messages，radio-- Subscribe to the mechanism and the authentication mechanism and the protection of data security and other functions，is also a lightweight，scalable and good，open—ended．Then the test platform, successfully transplanted to W5500 within the protocol. Again, for wirelesssensor CC2530 and connectivity,and with the Internet connectivity was proposed design idea and made a test lab．Finally,in the above experiment is proposed based on test platform based on the external hardware circuit design ideas and hardware circuit design．
Keywords: Internet of things; ZigBee ; Gateway;CC2530;W5500
