  • 본 논문에서는 센서 네트워크에서 수명을 늘리기 위한 기존의 통신 프로토콜 중에서 모바일 에이전트가 있는 환경에서 전체 네트워크 트래픽 량을 줄여 더욱더 수명을 늘리기 위해서 클러스터를 도입한다. 고정된 위치에서 싱크가 데이터를 수집할 경우 싱크 한 홉 내에 있는 노드들이 에너지를 빨리 쓰기 때문에 네트워크 파티션이 일어나기 쉽다. 이를 해결하기 위해 모바일 에이전트를 이용하여 네트워크 수명을 연장하는 방법이 연구되었다. 하지만, 모바일 에이전트가 이동을 하게 되면 전체 네트워크의 트래픽 양이 많아진다. 늘어난 트래픽을 줄이기 위해 모바일 에이전트가 있을 때 클러스터링의 성능을 분석하고 에너지 효율적인 클러스터 방법에 대해서 제안한다.

  • This paper presents auto-reclosing algorithms with reference to power system stability based on MAS(Multi-Agent System). And this paper shows auto-reclosing algorithms considering power system stability. It includes the variable dead time, optimal reclosing, sequential reclosing, emergency extended equal-area criterion(EEEAC) algorithm, and modified EEEAC algorithm. This paper divides Auto-reclosing algorithms into respectively agents according to their tasks. A separated agent is merely a software entity that is situated in some environment and is able to autonomously react to changes in the environment. And all the simulations in this parer were tested by EMTP MODELS.

  • A mobile agent is an autonomous software agent capable of moving from one computer to another while performing its tasks. We view the agent as a discrete event system in the view of its computation and communication. This paper presents a methodology far modeling and simulation of such a mobile agent system as a discrete event system. The methodology is based on the Mobile Discrete Event System Specification (MDEVS) formalism and the associated simulation environment AgentSim which are previously developed by the authors. Within the methodology an atomic model represents dynamics of a mobile agent; a coupled model is modeled as mobile agent servers for representation of structural changes between atomic agents. Being based on the object-oriented environment the modeling methodology exploits inheritance of basic classes AtomicModel and CoupledModel provided by AgentSim.

  • A pump design system was constructed by several integrating in-house programs and commercial softwares to design and evaluate centrifugal pumps. An agent-based prototype framework has been developed for collaborative design and optimization of a centrifugal pump. This paper introduces the feasible technology needed to construct a pump design system based on software agents. The integrated design system, developed in the present study, was used in designing a centrifugal pump and modifying its impeller shape by using optimization processes to increase the pump performance.

  • This paper presents animation techniques and issues involved in virtual environments where the participants interact with each other through a network. The state of the participant should be recognized at each local site, and broadcast to the other sites. Because information exchange is minimal, animation techniques are applied to convert the incoming low DOF parameters into high DOF joint angles that completely determine the configuration of the agents at each frame. As a case study, a software system VRLOCO is introduced, which has been developed by the author over the last five years. From a simple stream of body center positions, VRLOCO generates realistic curved path human locomotion in real-time. Based on the heading direction and speed, the locomotion automatically switches among five different primitives: walking, running, lateral stepping, backward stepping, and turnaround. The techniques presented here proved robust and faithful: the algorithm is not sensitive to the noise in the data, and the resulting animation conforms well with the original data.

  • Since 1996, the document exchange method by EDI has been introduced in port and logistics industries in Korea to enhance the declaration activities to the Pusan Port Authority and Customs. In spite of these efforts, users such as shipping companies, shipping agents, and freight forwarders have complained the inconvenience of using EDI systems. The major reasons can be summarized as follows: repetitional EDI transfer, too much transfer time, inconvenient EDI software, and problems on message receiving confirmation. Furthermore, EDI has been used only for transmitting messages. To solve these problems, this study has adopted the integration system by applying the concept of SCM to logistics system by XML/EDl. In the view of SCM, the existing EDI has some problems because its role is only to transmit the messages. This paper is to suggest how current EDI systems in Port and logistics sector has to be chanced by Introducing SCM. The integration system gives us such advantages as accuracy of cargo data, integration of processes among firms, and keeping the trace of cargo.
