Real-e ProjectReliable Architectures for
Adaptive and Mobile e-Learning Applications

• Project Description

Andreea Monnat LASSY Seminar January 25, 2004
2
Main Objective

• Propose an architectural model for reliable,
  adaptive and mobile e-learning applications using
  the mobile agents paradigm.

3
Background

• Mobile agent Software abstractions that can
  migrate across the network representing users in
  various tasks.
• Characteristics of a mobile agent
• Use of active objects (objects that move from
  place to place and at the destination they can
  obtain a thread of control automatically)
• Interactions with various environments to find
  out information
• Ability to obtain information or performs actions
  on behalf of the sender
• Ability to report the works results to the
  requesting person
• Ability to make decisions on behalf of the person
  it represents.

From Client-Server to Mobile Agents

• Scalability issues for many users
• Bandwidth/latency code shipping versus data
  shipping
• solution could be the use of mobile agents
• All the evaluation engine information can be
  transferred in one step gt reduces network
  communications
• User has access to all required information
  instantly
• User assessment can be performed on the clients
  computer

5
Scenarios for Using MA

• a piece of software could play for example the
  role of a
• Monitor Agent creating a user profile (areas
  of interest, learning speed, learning techniques)
• or a Tattletale Agent user progress tracking

6
Research Framework
Capturing privacy and security requirements for
mobile LMS
Formal verification of dependability properties
of the reference architecture

Discussion

• Use of FIDJI methodology?
• strong mobility or weak mobility?
• Analysis model can UML model agent mobility?
• Agent UML? Extensions?
• Security is still the main issue in MAS. Which is
  the more adequate MAS for our purposes?
• A solution could be the integration of the mobile
  agents within the Jini (EJB?) framework.
• The agents have to be FIPA compliant.
• Have the agents to be also SCORM compliant? Do we
  need a specific LMS?
• The JADE agent middleware seems to be an adequate
  MA platform for our purposes.
• Can JADE mobile agents be integrated within Jini?

Work Packages

• WP0
• organize adequate collaborations on LMS and
  mobile agents.
• Provide SoA for LMS and MAS.
• WP1
• Decision on the project methodology.
• Provide a case study.
• Define the requirements document
• WP3
• Design modeling based on the chosen methodology
• WP4
• Partially formal verification of systems
  properties (using HOPi?, Mobility Workbench? PN?)
