• Current state – Agents middleware– Prototype application– Test Environment

• Which way now?– Inspection of our architecture– Review of intelligent agent’s framework– Choice of service

Overview

CAMELs

• This research is a part of the project CAMeLS.

• CAMeLS:– Context-Aware Mobile eLearning Services– Agent-oriented InfoStation-based middleware

Current state:

Agent’s middleware on InfoStation

• MailChecker– Scenario-based application– Check periodically for new e-mails– Alert user by sending notification to MD

• Using Bluetooth– Support multiple MDs– Support notification cashing

• Send notification when MD comes into IS range – Works equally well with simulated Bluetooth link and

with real devices

Current state:

Sample Prototype Application

• Simulated Environment– Rococo Impronto Simulator;

– WTK Sun Java Wireless Toolkit for CLDC;

– BlueCove Emulator + Micro Emulator.

• Real Environment– Sony Ericsson (P1i and k750)

– Nokia (N73)

Which way now?

(Intelligent) Agent’s Framework

• Current used agent’s framework– JADE

• Future choice of intelligent framework:– JADEX (JADE extension) - University of Hamburg– CybelePro – Intelligent Automation, Inc.

ELF

• The ELF is an international effort to develop a service-orientated approach to the development and integration of computer systems in the sphere of learning, research and education administration.

Which way now?

Our choice for service

• We chose to develop service mTest.So we will make the first tests of our architecture.

Thank you for your attention!
