Comparison and Analysis of DNS and DOA for Internet of Things Naming System

In this paper, a couple of naming systems for Internet of Things(IoT) are surveyed, analyzed and compared. Firstly, a traditional naming system, Domain Name System(DNS) of Internet Engineer Task Force(IETF), is introduced. In addition, several challenges faced by DNS in the IoT are described. Secondly, the newly upcoming naming system, Digital Object Architecture(DOA) of International Telecommunication Union Telecommunication Standardization Sector(ITU-T), is analyzed. And then, these two kinds of naming systems are analyzed and compared from a variety of views.
