Abstract

In this paper, we analyzed the known agent tracking models and proposed a new agent tracking model based on the distributed event service that always assures reliable tracking. Also we experimented the Performance of the event servers on the agent monitoring system that implements the distributed event service and showed their performance to decrement gracefully. The proposed tracking model doesn't make only several clients trace a mobile agent which moves among agent servers autonomously, but also supports two types of agent tracking agent location tracking that notifies agent location to the clients and path establishment that maintains reliable connection between agent servers for message delivery.

본 논문은 이동 에이전트를 추적하는 기존 메커니즘들을 심층 분석하여 문제점을 도출하였고, 이러한 문제점을 해결한 분산 이벤트 서비스 기반 에이전트 추적 모델을 제안하였으며, 이를 적용한 에이전트 감시 시스템을 구현하여 제안한 추적 모델의 성능을 분석하였다. 안한 에이전트 추적 모델은 에이전트 이동이 발생하여도 에이전트 추적이 항상 가능하며, 다중 클라이언트가 동시에 한 에이전트를 추적할 수도 있게 한다. 그리고 에이전트가 이동할 때마다 이를 추적하는 모든 클라이언트에게 위치를 알려주어 클라이언트가 항상 정확하게 에이전트 위치를 파악할 수 있게 하는 위치추적 유형과 메시지를 전달하는 통로를 항상 신뢰할 수 있는 상태로 설정하는 경로설정 유형을 모두 지원한다.
