A Study On Some Key Technologies Of IoT Devices Management Platform

Since the concept of Internet of Things(Io T)was brought forward,a growing number of Io T applications and services have come into our lives.Smart service in ubiquitous environment has gradually become the focus of research at home and abroad.However,most of the Io T application systems at present are relatively independent.Also,their functions are single,and different application industries have different ways of information transmission and processing.There are also some problems such as inconsistent data between application systems,difficulty in resource reuse and the lack of interconnection mechanism.Therefore,how to provide a device resource management platform for the Io T to shield the heterogeneity of application subsystems is of great importance.This thesis focuses on several important issues in the design of Io T resource management platform.Firstly,the resource representation model for Io T service is proposed.The role of resource representation model in Io T is like to the significance of database schema to web information system.In this thesis,the basic structure of traditional Internet resource reference model OWL-S will be referenced and modeled appropriately for Io T.Then a resource representation model for Io T is proposed and verified by simulation.To some extent,this model can provide theoretical support for the unified description of Io T services and resources.Secondly,a multi-terminal selection algorithm for Io T services is studied.How to rationally configure the best terminal set for each user's business under the condition of resource constraints to improve the utilization efficiency of the ubiquitous peripheral resources is the point.Therefore,this problem is modeled as a multi-terminal aggregation problem based on the service model and resource model of the business layer.At last,it is abstracted into a mathematical combinatorial optimization problem and solved by heuristic ant colony optimization algorithm.Finally,a design structure and implementation of device management platform for Io T is proposed.Driven by complex business scenarios in ubiquitous environments,this architecture builds a Io T smart service system oriented to all walks of life and breaks the isolation of "information island".At last,the smart service access platform based on B/S and C/S mode is designed,and several typical Io T application scenarios are validated.
