Based on analyzing IoT two basic concepts

architecture of IoT is proposed

which includes underlayer network distribution

convergence gateway access

inter-connected network integration and terminal user application.In the architecture

a protocol structure of IoT is given

which consists of network protocol layers

network control platform and application terminal platform

and the key technologies for IoT have been discussed concerning hardware and software.Six development conceptions of future IoT have been presented based on summarizing the existing problems of IoT in standards

technologies

security and application.
