一种基于Chord的物联网信息服务方法

摘要

This paper presents a structured P2P-based information service method in Internet of Things. First, according to the characteristics of the information production in Internet of Things, the paper proposes the basic information production model in Internet of Things. And then by analyzing the traits of information service in Internet of Things, a Chord-based information service node form method and the corresponding information storage and query methods are proposed. The theoretic analysis and the comparison with the EPC network indicates that the Chord-based information service method can avoid performance bottlenecks of system, and can effectively improve its security, robustness and efficiency.%　　文章提出了一种物联网中基于Chord的信息服务方法。文章首先根据物联网中信息产生的特点提出了物联网中的基本信息产生模型，然后通过分析物联网信息服务的特点并以Chord网络模型为基础，提出了一种基于Chord的信息服务节点组织方法，并给出了相应的信息存储和查询方法。经过与EPC网络架构进行的分析比较，这种基于Chord的P2P信息服务方法能够有效消除系统性能瓶颈，并能提高系统的安全性，健壮性和工作效率。
