Abstract

In recent years, various services in mobile environments due to the growth of mobile devices and related techniques like wireless networks. Furthermore, as the increasing communication traffic in cellular networks has become a new significant issue, many studies for device-to-device(D2D) communication and D2D-based cooperative services have been performed recently. In this paper, we design a smart agent system for D2D-based cooperative services and propose a dynamic service binding method based on service ontology. We classify roles of mobile devices for cooperative services by defining three types of smart agents, and construct a knowledge base in order to describe properties of 'service' unit. The proposed knowledge model, D2D cooperative service ontology, can enable a autonomous cooperative services between mobile devices by binding a requested service to the appropriate member device according to the real-time context in mobile environments.

최근에는 모바일 기기 자체의 성능뿐만 아니라 무선 네트워크 등의 연관 기술들이 발달함에 따라 모바일 환경에서의 다양한 서비스에 대한 관심이 높아지고 있는 추세이다. 게다가 급증하는 통신 부하 문제가 새로운 이슈로 떠오르면서 단말 간 직접 통신(D2D)과 이에 기반한 단말간의 협력 서비스 방식에 대한 연구가 활발해지고 있다. 본 논문에서는 D2D 기반의 협력 서비스를 위한 스마트 에이전트 시스템을 설계하고 서비스 온톨로지 기반의 동적 서비스 바인딩 기법을 제안한다. 3가지 타입의 에이전트를 설계하여 협력 서비스를 위한 역할을 구분하고, 에이전트의 기능을 서비스 단위로 모델링하여 속성을 기술함으로써 지식 베이스를 구축한다. 제안한 지식 모델인 D2D 협력 서비스 온톨로지는 실시간의 상황이 지속적으로 변화하는 모바일 환경에서 가변적인 상황에 따라 필요한 서비스를 최적의 멤버 기기에게 동적으로 바인딩함으로써 효율적이고 자율적인 협력 서비스를 가능케 할 수 있는 핵심 기술이라 할 수 있다.
