Abstract

One of powerful software paradigms for distributed systems is a mobile agent system. Since the usage of mobile agent systems is increased, a software development model to construct softwares efficiently for these systems is needed. Currently, UML is a widely used software development model. However, existing UML can not describe the necessary mobility of the mobile agent based software systems in explicit way. In this paper, the interaction diagrams of UML(sequence diagrams and communication diagrams) are extended and used to express the mobility of the mobile agents including the functions of platforms of mobile agent systems in three ways. For a case study, we applied the extended diagrams to a distributed file searching using mobile agents, and we confirmed these diagrams can describe the function and mobility of mobile agents very well.

분산 시스템을 위한 강력한 소프트웨어 패러다임 중 하나가 이동 에이전트 시스템이다. 이동 에이전트의 사용이 증가하고 있으므로 이 시스템을 효율적으로 구축하기 위한 소프트웨어 개발 모델이 필요하다. 현재 소프트웨어 개발 모델로서 널리 사용되고 있는 것이 UML이다. 그러나 기존의 UML은 이동 에이전트 기반 소프트웨어 시스템을 개발하는 모델로 사용하고자 할 때 이동성을 명시적인 방식으로 기술할 수 없다. 본 논문에서는 UML 다이어그램 중 상호 작용 다이어그램(즉 순차 다이어그램과 통신 다이어그램)을 확장하여 세 가지 방법으로 이동 에이전트의 이동성을 명시적으로 표현하였는데 이동 에이전트를 위한 플랫폼의 기능도 포함하였다. 확장한 다이어그램의 표현법을 사용한 사례연구로 이동 에이전트를 이용한 분산형 파일 검색에 적용하였으며 이동 에이전트의 기능과 이동성을 잘 표현할 수 있음을 확인하였다.
