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 for modeling and simulation of such a mobile agent system as a discrete event system. The methodology is based on the Mobile Discrete Event System...

A mobile agent is self-governing software that has one or more goals and can migrate from one node to another in a network. Mobile agent has received pervasive interest in both research and academia in recent years because of its support for asynchronous and disconnected operation capability in distributed system Along with these affirmative sides, the full scale adoption of mobile agent has be...

Mobile agents have emerged as a new computing alternative and are proving to be more flexible and dynamic than the classical client-server model. In the mobile agent model the program is sent to and runs on the remote site, thereby operating closer to and more interactively with the remote document resource. AgentSys is a mobile agent system that implements the protocols necessary to allow agen...

1. PROBLEM STATEMENT – METHODOLOGICAL SUPPORT FOR SYSTEMS WITH AGENT MOBILITY? A property of agents is the ability to move from one host to another to perform computations. While not all agents require such a property, agent mobility has been recognized as beneficial in a number of applications and a sizable number of mobile agent toolkits have been developed for mobile multiagent applications....

Logical or virtual networks based on mobile agents exhibit a high level of internal dynamics: Agent servers and services are added, deleted, or modified, connection quality changes over time, etc. In addition, the size of these networks steadily grows, as practical experience shows, and adds a quantitative factor that makes scalable solutions and structures mandatory. These aspects cannot be ha...

One of the key arguments for mobile agent systems is the flexible usage of groups of agents. However, none of the existing mobile agent systems supports agent groups. In this paper we introduce our model of agent groups in mobile agent environments. Various entities of an agent group are consecutively identified and their roles within an electronic market scenario thoroughly pictured. We argue ...

Mobile agent technology has received a rapidly growing attention over the last few years. A number of mobile agent systems are under development in academic as well as industrial environments, there are already various moves to popularize and standardize mobile agent facilities and architectures. It has been argued that mobile agents provide certain advantages as compared to traditional approac...

The paradigm of mobile agents offers a powerful and flexible opportunity to develop distributed applications on a high-level of abstraction. One of the most interesting tasks for mobile agents is an active search for relevant information in non-local domains on behalf of their users. A mobile agent will be sent out on behalf of an user to various host servers in the Internet and to find informa...

Mobile agent technology has gained more importance recently due to the rapid advance of high-performance mobile devices with high-speed wireless telecommunications technology such as 3G. However design methodologies for mobile agent applications are not mature enough to support their software development process. We proposed an extension of Activity Diagrams in UML 1.5 for modelling mobile agen...

One of the major setback preventing the mobile agent technology from being widely exploited is a lack of interoperability between heterogeneous mobile agent systems. In this paper we propose a Java-based framework which enables high-level interoperability between Javabased mobile agent systems. The framework relies on an event-driven, proxy-based mobile agent model and allows for supporting int...
