3. 3 ARCHITECTURE OF MOBILE AGENT We proposed a model to characterize the mobile agent system architecture Mobile Agent virtual society was composed within three cells –Pico cell –Micro cell –Macro cell The Pico cell represented the client mobile agent The Micro cell constituted by at least one client mobile agents (Pico cells) and one server agent Several Micro cells construct a Macro cell

4. 4 PICO CELL(CLIENT AGENT) Consists of Client profiles Object function loader Role setting components selector

5. 5 MICRO CELL CONSISTS OF Agent Profiles/Database, Server Agent Web Server Agent Profile and Database consists of User personal environment setting information User Log Files User personal information User submitting results

6. 6 SERVER AGENT CONSISTS OF Verification components Communication components Management components Roles setting objects (agent characteristics) Provider
