초록

사물 인터넷 (IoT : Internet of things) 환경에서 여러 종류의 스마트 디바이스들은 스마트 헬스케어 서비스와 같은 원격 모니터링 서비스를 제공하기 위해 4G/5G, WiBro, 블루투스 등의 다양한 네트워크 기술을 통해 인터넷에 연결된다. IETF Mobile IP 기반의 대부분의 국제표준 인터넷 이동성 관리 기술은 IoT 환경에서 디바이스들이 가지고 있는 제한적인 전력, 제한적인 CPU 처리 및 메모리 능력 및 과도한 시그널링 오버헤드로 인해 사물인터넷 환경에 적합하지 않다. 본 논문에서는 IoT 환경에서 신뢰성있는 이동성 관리를 위해 IETF CoAP에 기반한 새로운 이동성관리 프로토콜인 CoMP (CoAP-based Mobility Management Protocol)를 제시한다. CoMP는 Constrained 환경에서도 신뢰성 있게 이동성관리를 제공할 수 있는 장점을 제공한다. CoMP의 구조 및 알고리즘을 제시하고, 마지막으로 수학적 분석과 시뮬레이션을 사용하여 성능평가를 하였다.

In Internet of Things (IoT) environment, a variety of smart devices are connected to Internet through various network technologies such as 4G/5G, WiBro, Bluetooth, etc. in order to provide the remote monitoring service such as smart healthcare service, etc. Most standard mobility management protocols based on IETF Mobile IP may not be suitable for Internet of Things (IoT) environments due to constrained power, constrained CPU processing and memory capacity, and large signalling overhead which are inherently accompanied by various devices in IoT environments. In this article, we propose a new mobility management protocol CoMP (CoAP-based Mobility Managemenbt Protocol) for reliable mobility management in IoT environments. The architecture and algorithm to achieve both reliability and simplicity for IoT mobility management are proposed. Finally, performance has been evaluated by both mathematical analysis and simulation.
