物联网体系结构模型与互连机理

The research of IoT architecture model and internetworking mechanism

网络实现了信息资源的共享,极大地改变了人们的生产生活方式.物联网将网络从信息空间进一步向物理空间延伸,通过对物理环境的感知与控制,丰富了人类认识世界与改造世界的手段.本文首先提出了包括对象感控层、数据交换层、信息整合层和应用服务层等4个层次的物联网体系结构功能模型,并对体系结构模型及各层实体进行了面向对象的描述.对于物联网系统中最为核心的网元互连问题,我们兼顾考虑强弱网元间的互连互通和网元与物理对象间的互动互操作,提出了支持强弱网元共存的物联网互连模型和基于能力映射与任务迁移的强弱网元互连机制.论文通过原型系统对提出的互连模型和互连机制进行了验证.

Networks have greatly changed people＇s production and life through the information sharing. Internet of Things（IoT） is an extension of the networks to the physical space. By sensing and controlling the physical environment, IoT enhances our ability of understanding and changing the world. This paper proposes the functional model of IoT architecture with four hierarchical levels, including object sensing and controlling layer, data communication layer, information integration layer, service application layer. Then we present the object-oriented description of the architecture model and the main entities of each layer. For the internet working issue, which is the core problem of the IoT architecture, we propose an internetworking model supporting the coexistence of the strong and weak network elements. We present the internet working mechanism between the strong and weak network elements based on the ability mapping and task transfer. We verify our proposed internetworking model and mechanism through the prototype.
