| 摘 要： | 物联网具有数据量大,节点异构且分布广泛等特点。采用副本存储可以提高数据访问性能。针对物联网中对副本定位快速高效要求的问题,提出一种基于小世界的类-域层次的物联网中副本定位方法。从物联网中数据访问的局部聚类性考虑,将节点划分为类层次和域层次,分别采用根据类-域数据访问特点的双向环形消息扩散机制,实现副本的局部和全局定位,从而提高副本定位的效率。

| Abstract: | Internet of Things has a large amount of data,heterogeneous node,extensive distribution,etc.Replica can improve data access performance.According to the requirements of fast and efficient replica location for the Internet of things,a replica location method based on the class of small world-the class level and the domain level in the Internet of Things is presented.From the local clustering of data access in the Internet of Things,nodes are divided into the class level and domain level.Given the class-domain data access characteristics,two-way circular message diffusion mechanism to achieve replica of the local and global location is proposed to increase the replica location efficiency. |
