DNS naming services for service discovery and remote control for Internet-of-Things devices

摘要

This paper proposes the service discovery and the remote control for Internet-of-Things (IoT) devices based on the Constrained Application Protocol (CoAP) and Domain Name System (DNS). As the number of devices increases, the manual configuration of domain names and services might be unmanageable for users. A legacy DNS Name Autoconfiguration (DNSNA) for IPv6 networks can be used to register the DNS names of IPv6 devices automatically into a DNS server. However, DNSNA is not applicable for the service discovery and remote control because of providing only for the DNS names of IoT devices. Therefore, we provide a strategy, which is suitable for IoT devices based on the CoAP. Our proposed remote control architecture is based on a standard protocol called CoAP for IoT devices, which have limited computing power. It uses using DNSNA to provide appropriate services to our remote control system. In this scheme, an IoT device can register its DNS name and service list into a DNS server. Through our remote control system, users can autoconfigure devices and their services. Thus, we can easily monitor and remote-control any IoT device using a smartphone or tablet PC.
