Introduction to Pervasive Computing

What is Pervasive Computing “The most profound technologies are those that

disappear. They weave themselves into the fabric of everyday life until they are indistinguishable from it” – Mark Weiser

Example of pervasive technology – “Writing” Writing vs. current computer usage

What is not Pervasive Computing. The ability to carry computers at beach, jungle or

airport Virtual reality – ‘A world inside computer’

UDIC Presentation

Example of Pervasive Computing. Follow Me

Files, Music … Global Access

At home, In office, at KFC … Services

What can I do for you? Know you know me

Who’s the Boss?

UDIC Presentation

Whole lots of issues

UDIC Presentation

Some Issues

Effective use of smart spaces. Invisibility. Localized Scalability. Privacy and Security. Implementation Issues.

User Intent. Cyber Foraging. Client Thickness. Context Awareness.

UDIC Presentation

Our Work : Problem Space

Pervasive computing systems developed till now are ad-hoc.

Isolated Autonomous systems. There is lots of information present

on web which is not organized and utilized by us.

UDIC Presentation

Scenario 1

Mr. X

His Boss

Office

Club

Hospital

UDIC Presentation

Our Work : Vision

Humans, devices and abstract concepts … all will have unique identity.

Using power of semantic web to share information over the web, protecting privacy of individual at the same time.

UDIC Presentation

Our Work : Concept

Autonomous System

Unit1

Unit2

Unit3

AS Head

Device1

Device2

Device3

UDIC Presentation

Our Work : Concept

AS Head AS Head

AS Head

UDIC Presentation

Our Work : Identity

Every Autonomous system will have unique URI (ex: uri://umkc.edu/AS1)

One can extend the URI within the AS EX(uri://umkc.edu/AS1/G1)

(uri://umkc.edu/AS1/G2) Every sensor device will have ID

URI (ex: uri://umkc.edu/AS1/G1/S1)

UDIC Presentation

Our Work : Semantic Web Each type specification will point to

a rich semantic description on the semantic web

Has information like Functionalities Technical details Inputs/Outputs

UDIC Presentation

Our Work : Pervasive Profile

Profile has all user information has security policies

Personal profile has a unique URI Personal server can be any device

which can give me profile URI

UDIC Presentation

Our Work : Pervasive

Authentication

Biometric authentication Pervasive profile gives user

authentication inputs Global identity/ Local

authentication

UDIC Presentation

New concept – Pervasive services. These are the services which are

described on the web. If you want to implement them you just need to get the description at your end and you will be ready to use this service.

Our Work : Pervasive Service

UDIC Presentation

Semantic Service descriptions on semantic web with the URI

Analogous to DAML-S descriptions Dynamically configurable services

Example “Pervasive Buddies”

Our Work : Pervasive Service

UDIC Presentation

This approach is on an abstract level

Global pervasive computing woven across semantic web

Make sensors do basic work, while managers interpret the semantics and drive the sensors together to provide service(s) within the AS.

Our Work : Conclusion

UDIC Presentation

Next Steps

Current Pervasive Approaches – Frameworks / Tools Project Oxygen (Project Oxygen,

Computer Science and Artificial Intelligence Laboratory,MIT)

Project Aura ( CMU ) Project Cobra (eBiquity

Research Group UMBC )

UDIC Presentation

Next Steps

Device Ontology Integrate with upper ontology –

SUMO/CYC User Profiles

Likes / Interests Service Ontology

Service description / High-level language (scripting)

UDIC Presentation

Next Steps

Semantic Web Pervasive Computing Framework

Service discovery Service Composition/Matching Device auto configuration Autonomous system management Policy enforcement

Security and Authentication Biometric Authentication / profile access
