Implementation of the Mobile Agent System providing Agent Mobility & Agent Cloning using Resource Allocation Problem

摘要

A mobile agent is a program that autonomously migrates from machine to machine in a heterogeneous network, interacting with services at each machine to perform some desired task on behalf of a user. As a mobile agent migrates from machine to machine in a heterogeneous network the environment in which it operates changes. The ability to adapt to dynamic environment and unexpected events is a key issue for mobile agents. In this one, we first present a model of adaptive mobile agents. We then discuss the implementation of a task execution system based on adaptive mobile agents. On each machine it interacts with service agents and other resources to accomplish its task, returning to its home site with a final result when that task is finished. Characteristics of mobile agents include agent mobility, object passing, autonomous, asynchronous and parallel Execution. The main reasons to use mobile agents in distributed applications are they reduce network load, execute asynchronously, autonomously, adapt dynamically and they are naturally heterogeneous. Mobile Agent System provides the features of agent mobility, creation and termination of agents, agent cloning & getting the results of completed tasks from the other agents.
