  • Recently, due to the widely use of personal computers and internet, many computer users requested intelligent system that can cope with various types of requirements and user-friendly interfaces. Based on this background, researches on the intelligent agent are now activating in various fields. In this paper, we modeled, designed and implemented an intelligent agent system for pattern classification by adopting intelligent agent concepts. We also investigated the pattern classification method by utilizing some pattern classification algorithms for the common data. As a result, we identified that 300 3-dimensional data are applied to three pattern classification algorithms and returned correct results. Our system showed a distinguished user-friendly interface feature by adopting various agents including graphic agent.

  • An agent is a computer program that acts autonomously on a computer system. A mobile agent is not bound to the system where it begins execution. It has an ability to transport itself from on e system in a network to another. Mobile agent system solve the network traffic problem. Moreover, the agent may utilize the object services of the destination agent system. In this study the mobile agent system is introduced to support security service.

  • The active rule system is a key element of the rule-based mobile agent middleware system for activeness and autonomy of the sensor network. The rule manager, which is the main components of active rule based mobile agent framework and active rule system, performs the control and management of the rule-related processes. In this paper, we design and implement the roles and functions of the rule manager in detail. The proposed rule manager plays an important role in the sensor network environment. The sensor data server loads the active rule on the mobile agent by the rule manager according to the situations, and the mobile agent migrates to the destination node and performs the designated action. This active rule-based mobile agent middleware system presents the usefulness for the various sensor network applications. Through the rule execution experiment using the rule-based mobile agent, we show the adaptability and applicability of rule-based mobile agent middleware system to the dynamic environmental changes in sensor networks.

  • In this study, we investigated the modeling and design of an Intelligent Agent System (IAS). To achieve this goal, we introduced several kinds of agents that exhibit intelligent features. These are the main agent, management agent, watcher agent, report agent and application agent. We applied the intelligent agent concept to two different application fields, i.e. the intelligent agent system for pattern classification and the intelligent agent system for bank asset management modeling.

  • The computer security is considered important due to the side effect generated from the expansion of computer network and rapid increase of the use of internet. Therefore, Intrusion detection system has been an active research area to reduce the risk from intruders. A number of advantages of using mobile agent computing paradigms have been Proposed. These advantages include : overcoming network latency, reducing network load, executing asynchronously and autonomously, adapting dynamically, and operating in heterogeneous environments. Many information security models have been proposed to mitigate agent-to-agent. agent-to-platform, and platform-to-agent element risks . In these paper, We have an object which is that through intrusion detection system development, the mobile agent is managed and through the analysis of performance data. the best environment is served.

  • A RMON agent system, which locates on a subnet, collects the network traffic information for management by retrieving and analyzing all of the packets on the subnet. The RMON agent system can miss some packets due to the high packet analyzing overhead when the number of packets on the subnet is huge. In this paper, we have developed a light-weight RMON agent system that can handle a large amount of packets without packet loss. Our RMON agent system has also been designed such that its functionality can be added dynamically when needed. To demonstrate the dynamic reconfiguration capability of our RMON agent system, a simple port scanning attack detection module is added to the RMON agent system. We have also evaluated the performance of our RMON agent system on a large network that has a huge traffic. The test result has shown our RMON agent system can analyze the network packets without packet loss.

  • 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.

  • Advance in Internet technology has changed traditional production planning and control methods. In particular, collaborations between participants in supply chains are being increasingly addressed in industry for enhancing chain-wide productivity. A representative paradigm that emphasizes collaboration in production planning and control is CPFR(Collaborative Planning, Forecasting and Replenishment). In this paper, we present a multi-agent system architecture that supports the collaborations specified in CPFR. The multi-agent system architecture consists of event manager, data view agent, business rule agent, and collaboration agent. The collaboration agent systematically controls negotiation between supplier and buyer with the aid of collaboration protocol and blackboard. The multi-agent system has been implemented with EJB(Enterprise Java Beans).

  • 인터넷과 World Wide Web의 폭발적인 성장은 네트워크에 많은 정보와 리소스를 제공하고 있다. 그렇지만, 대부분의 사용자들에게 있어서 인터넷 리소스의 사용은 Bandwidth에 의하여 많은 제한을 받고 있다. 그러나 애플릿 방식을 통해서 HTML이 가지고 있는 정적인 면과 CGI의 bandwidth에 따르는 성능 저하 문제를 해결할 수 있다. Mobile Agent는 사용자의 특정 목적을 성취하기 위해서 사용자의 컴퓨터에서 출발하여 네트워크를 이동하면서 작업을 수행한다. 이렇게 수행할 수 있는 코드가 네트워크를 통하여 전송되고, 네트워크에서 수행되기 때문에, 자연스럽게 mobile code의 보안에 중요한 문제가 발생한다. 본 연구에서는 이러한 Mobile Agent를 사용하는 분산 웹 환경에서, Mobile Agent를 호스트와 Agent를 보호할 수 있는 방안을 모색보고, Mobile Agent 의 개념과 Mobile Agent를 구성하면서 생기는 문제를 기술하고, 이러한 문제를 해결하기 위해서 연구중인 방법을 제시하고, 제시된 방법 중에서 현실적으로 적용 가능한 방법을 사용하여 이동 에이전트의 보안 시스템을 설계해 보도록 한다.

  • 멀티 에이전트 시스템은 공통의 목표를 위해 함께 일하기로 합의한 협업 에이전트로 구성된다. 에이전트 시스템에서 메시지를 스케줄링 할 때, 동일한 우선순위가 역할의 중요도를 고려하지 않고 모든 에이전트에게 동일하게 할당된다면 성능은 극대화되지 않을 것이다. 본 논문에서 우리는 새로운 메시지 기반 우선순위 스케줄링 기법을 제안한다. 그것은 에이전트 시스템으로 하여금 에이전트와 메시지 작업 처리량의 중요도에 기반으로 메시지의 우선순위를 적절하게 모델링함으로써 환경 변화에 신속히 적응할 수 있게 한다. 에이전트 시스템의 성능은 저자들에 의해 개발된 에이전트 플랫폼을 통해 실행된 범죄 예방 시스템에 대한 사례 연구를 이용한 제안된 계획에 의해 상당히 개선된 것으로 보여준다.
