Abstract

This paper proposes an adaptive inter-agent communication protocol to considerably reduce the amount of agent location information maintained by each service node and the message delivery time while avoiding the dependency of the home node of a mobile agent. To satisfy this goal, the protocol enables each mobile agent to autonomously leave its location information only on some few of its visiting nodes. Also, it may significantly reduce the agent cache updating frequency of each service node by keeping the identifier of the location manager of each agent in the smart agent location cache of the node. Simulation results show that the proposed protocol reduces about $76%{\sim}80%$ of message delivery overhead and about $76%{\sim}79%$ of the amount of agent location information each service node should maintain compared with the traditional one.

본 논문에서는 이동 에이전트의 홈 노드에 대한 의존성을 피하면서 각 서비스 노드에 의해 유지되는 에이전트 위치정보량과 메시지 전달 시간을 매우 줄이는 적응적 에이전트간 통신 프로토콜을 제안한다. 이러한 목적을 달성하기 위해, 제안된 프로토콜은 각 이동 에이전트가 자율적으로 단지 자신이 방문한 노드들 중 일부분에게만 그 에이전트의 위치정보를 남겨두도록 한다. 또한, 이 프로토콜은 각 서비스 노드의 스마트 에이전트 위치 캐쉬에 각 에이전트의 위치관리자 식별자를 유지하게 함으로써, 노드의 캐쉬 갱신 횟수를 매우 줄일 수 있다. 본 논문에서 수행한 시뮬레이션에서는 제안된 프로토콜이 기존 프로토콜에 비해 메시지 전달 비용을 $76%{\sim}80%$ 정도 줄이고, 각 서비스 노드가 유지해야 할 에이전트 위치정보량을 $76%{\sim}79%$ 정도 줄인다는 것을 보여준다.
