(100x per decade)– Aggregate bandwith x2 in 8 months– 1.5 billion mobile phones in the next few

years– Devices / Users >> 1

The GoalThe Goal

Maximize the Enterprise productivity while

minimizing constraints brought by mobility

Research VisionResearch Vision

Not just about making applications mobileBut

Allowing enterprise applications to be deployed (used) in many different environments effectively.

Innovative workplace technologies and concepts in a variety of mobile work situations.

Demonstrate reference models, architectures and technologies that enable mobile enterprise roles to co-operate.

Context ManagerContext Manager

Observation and reporting of information relevant to the current “context” of devices, networks, users, applications

Based on Composite capability/preference profile (CC/PP)– Repository in RDF/XML (standardized

vocabularies, extensible, indirect references)– Context exchange protocol

Adaptability ManagerAdaptability Manager

Adapt to context changes– Security, Presentation, Usage of Network,

Enterprise Application specifics ... Changes in context are mainly due to

– mobility of users, computers– disconnection

Adaptation can be handled externally or internally for an application

Policy ManagerPolicy Manager

Enforces “dynamic” enterprise policy specifications affected by mobility– Obligation, prohibition, permission

Takes into account – Standards like RM-ODP– Existing Policy Manager

Security ManagerSecurity Manager Enable security as intended and

required by an application irrespective of the – environment– device

Provide an application infrastructure to leverage technologies such as WAP-WTLS

Enables the maximum security available on a device– e.g., GSM phones with WAP and BlueTooth –

enable the best Close management of security aspects

– e.g., Certificate management [issue & expiry control]

RoadmapRoadmap

Forming the Ground – Flexible Architecture– Year 1: Pervasive Computing (Based on

existing Scenarios)– Year 2: Ubiquitous Computing (Zillions of

Devices) Using the Base

– Year 3: Extensions to Technologies/Architectures to support completely new Business Scenarios

There will be a strong overlap!
