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

PICO CELL(CLIENT AGENT)

Consists of• Client profiles • Object function loader • Role setting components selector

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

SERVER AGENT CONSISTS OF

• Verification components • Communication components • Management components• Roles setting objects (agent characteristics)

PROCESS MIGRATION REQURIMENTS

• Common execution language • Process persistence • Communication mechanism between agent hosts • Security to protect agents and agent hosts

OTHER COMPETING TECHNOLOGIES• Message passing systems• Remote Method Invocation (RMI)• Common Object Request Broker Architecture

(CORBA)

APPLICATIONS OF MOBILE AGENTS

• Parallel Computing

• Data Collection

• E-commerce

• Mobile Computing:

ADVANTAGES OF USING MOBILE AGENTS

• Protocol Encapsulation• Asynchronous and Autonomous Execution• Fault Tolerance

DISADVANTAGES OF MOBILE AGENTS

• security risk involved in using mobile agents – A malicious mobile agent can damage a host – A malicious host can tamper with the

functioning of the mobile agent
