面向物联网的时钟同步体系架构研究

摘要

Based on the insufficience of the study on the clock synchronization architecture of Internet of things, a new architecture is proposed for future reference.Firstly, the clock synchronization general architectures is proposed including adaptability level, organization level and region level.Secondly the adaptability level architecture is given, to resolve issues about the adaptability of Internet of things,and then the organization level architecture is given based on the concept of clock synchronization groups, to solve the issue of clock synchronization organization and management.At last, based on the concept of the regional network, the region level architecture is proposed to address clock synchronization accuracy and security issues.%由于基于物联网时钟同步体系架构相关研究成果的匮乏,提出一种面向物联网的时钟同步体系架构,为物联网时钟同步体系架构的深入探讨提供借鉴.提出了包括适应层、组织层和区域层的时钟同步总体架构,给出了时钟同步适应层架构,以解决物联网的适应性问题.为解决时钟同步组织管理问题,基于时钟群的概念给出了时钟同步组织架构.为解决时钟同步精确性和安全性问题,基于区域网的概念提出了时钟同步区域架构.
