Research And Implementation Of IoT Application Prototype System Based On Smart Phone

Smart phones have a broad popularity,good hardware and operating systems,and it equips with Bluetooth,WiFi,3G / 4G and other communication interfaces,so the smart phone can replace traditional fixed gateway as a new mobile IoT Gateway.Therefore,this thesis presents an Io T application prototype system based on an open Io T gateway by smart phone.The main researches of this thesis contain the following three aspects:First,this thesis designs the structure and functions of the smart phone gateway,and proposes a concept of virtualization layer on the smart phone.This virtualization layer cuts off the binding relationship between traditional applications and terminal devices,so that different applications can share the data of terminal devices.Then,this thesis designs the Io T application prototype system based on smart phone gateway.Specifically,the main features include using low power Bluetooth as communication and networking way of sensing terminal,and the device information management of cloud platform for users and third-party applications.Then we build up a complete IoT application prototype system with the smart phone gateway,and make it achieved.Finally,this thesis builds an experimental intelligent home environment with various types of sensing devices,and simulates the manners to access these devices information for different third-party applications.The results show that the system can provide good compatibility and data interoperability for sensor terminal and third-party applications,on the basis of providing basic device information management services.
