摘要
随着物联网的高速发展,各种异构的物理实体被连入网络形成海量的虚拟资源,从而在性能和功能两个方面都为名字服务带来了新的挑战.本文首先从性能角度对物联网名字解析服务和发现服务通过层次式DNS技术、扁平式DHT技术以及混合使用这两种技术实现的架构方案进行了深入的分析比较;然后从功能角度,针对异构兼容、对等解析、隐私保护等三个关键性的需求,梳理了物联网名字服务的最新研究进展;最后探讨了物联网名字服务在未来可能的发展趋势.
With the rapid development of Internet of Things（ Io T）,heterogeneous physical entities have been connected to the netw ork to form massive virtual resources,w hich bring many new challenges to the name service in both performance and functionality.From a performance point of view,w e firstly give an in-depth analysis and detailed comparison among different resolution services and discovery services w hich are based on hierarchical DNS technology,flat DHT technology or mixing the tw o technologies.Then from a functionality point of view,w e describe the latest research for the purpose of addressing three key issues：compatible for heterogeneity,equitable and federated resolution,and privacy protection.Finally,w e summarize the development trends of name service and indicate the future research directions.
