Research on naming service architecture of Internet of things based on DHT
基于DHT的物联网命名服务体系结构研究

According to the issues of root server overload, load imbalance and single point of failure in Object Naming Service of Internet of Things(IOT), a Name Service architecture based on the Distributed Hash Table(DHTNS) for the Internet of Things is proposed, which replace the tree structure with the ring structure. A clustering algorithm based on the physical network topology and depending on neighbors set is adopted to improve Chord. And a prototype of the IOT naming service is implemented. Simulation results and analysis show that the architecture enhanced anonymity, confidentiality, integrity and effectiveness of the IOT naming service, and has advantages such as quick query, load balancing, better scalability, single node of failure tolerance, etc.
