Abstract

As one of the most spotlighted research areas, these days, the Internet of Things (IoT) aims to provide users with various services through many devices. Since there exist so many devices in IoT environments, it is inefficient to manually configure the domain name system (DNS) names of such devices. Thus, for IPv6-based IoT environments, this paper proposes a scheme called the DNS Name Autoconfiguration (DNSNA) that autoconfigures an IoT device's DNS name and manages it. In the procedure for generating and registering an IoT device's DNS name, the standard protocols of the Internet Engineering Task Force (IETF) are used. Since the proposed scheme resolves an IoT device's DNS name into an IPv6 address in unicast through a DNS server, it generates less traffic than multicast-based mDNS (Multicast DNS) which is a legacy DNS application for the DNS name service in the smart home. Thus, the proposed scheme is more appropriate in multi-hop IoT networks than mDNS. This paper explains the design of the proposed scheme and its service scenarios, such as smart home and smart road. It also explains the implementation and testing of the proposed scheme in the smart grid.

최근 가장 주목받고 있는 연구 분야 중 하나인 사물인터넷(Internet of Things, IoT)은 네트워크에 연결된 매우 많은 디바이스를 통해 사용자에게 다양한 서비스를 제공하는 것을 목표로 한다. IoT 환경에서 IoT 디바이스는 매우 많은 개수가 사용되는데 각 IoT 디바이스에 대한 DNS(Domain Name System) 네임을 일일이 수동으로 설정하는 것은 비효율적이다. 따라서 본 논문에서는 IPv6 기반의 IoT 환경에서 IoT 디바이스의 DNS 네임을 자동으로 생성하고 관리하는 DNS Name Autoconfiguration(DNSNA)이라는 기법을 제안한다. DNS 네임을 생성 및 등록하는 과정에서 Internet Engineering Task Force(IETF)에서 재정된 표준 프로토콜을 이용한다. 본 기법은 유니캐스트로 DNS 서버를 통해 IoT 디바이스의 DNS 네임을 IPv6 주소로 레졸루션(Resolution)하기 때문에 멀티링크 네트워크 환경에서는 기존의 멀티캐스트 기반의 mDNS(Multicast DNS) 기법보다 트래픽을 적게 발생시킨다. 따라서 본 기법은 멀티홉으로 구성된 IoT 네트워크에서 mDNS 보다 더 적합하다. 본 논문은 제안한 기법의 디자인과 스마트 홈과 스마트 로드에서의 서비스 시나리오를 설명한다. 또한 본 논문은 스마트 그리드 환경에서 구현 및 테스트에 대하여 설명한다.
