The Agent Pattern for Mobile Agent Systems

This paper presents the Agent pattern, a design pattern useful to develop dynamic and distributed applications. The Agent pattern provides a clean and easy way to develop agent-based applications, mainly in open and large-scale distributed environments such as the Internet and application areas such as Electronic Commerce. The Agent pattern encapsulates a business specific class (a specialization of the Agent class), with some user identification and a specific security policy, providing distribution, security and persistence transparency. Furthermore, this paper presents a detailed application of this pattern in the AgentSpace framework, as well as a brief application to the Telescript and Aglets Workbench.
