Design And Implementation Of Mobile Information Collection System Based On Internet Of Things

With the rapid development of the Internet of Things(IOT) and the extensiveapplication of smart mobile terminals, mobile terminals play an increasingly moreimportant role in IOT applications. IoT applications are usually based on thecollection of massive amounts of information, so the combination of multi-sourceinformation collection and smart mobile devices will make Internet of Things go intopeople’s production and living more easily.This paper mainly focuses on the design of IoT gateway supporting multi-modeaccess, the authentication for mobile terminals accessing gateway, and the informationcollection strategy based on historical data of the moving path.The paper first analyzes the key issues of the mobile information collectionsystem based on IoT, and thus designs the framework of the system, then gives designand implementation of the system supporting ZigBee,3G and other multi-mode accessto IoT gateway. So smart mobile devices can access information of the underlyingwireless sensor networks via WiFi, etc; According to the characteristics of the gateway,the paper designs a gateway authentication protocol which is more secure and needs lesscomputation, so it can protect sensitive information in the sensor network. On the otherhand, considering the characteristics of the mobile terminals access gateway using WiFi,the paper proposes an information collection strategy based on mobile path. This solvesthe problem of long delay of mobile terminals getting connection with the AP andimproves the system throughput.
