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

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
• Whos the Boss?

Whole lots of issues
6
Some Issues

• Effective use of smart spaces.
• Invisibility.
• Localized Scalability.
• Privacy and Security.
• Implementation Issues.
• User Intent.
• Cyber Foraging.
• Client Thickness.
• Context Awareness.

7
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.

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.

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)

13
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

14
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

15
Our Work Pervasive Authentication

• Biometric authentication
• Pervasive profile gives user authentication
  inputs
• Global identity/ Local authentication

16
Our Work Pervasive
Service

• 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.

17
Our Work Pervasive
Service

• Semantic Service descriptions on semantic web
  with the URI
• Analogous to DAML-S descriptions
• Dynamically configurable services
• Example Pervasive Buddies

18
Our Work Conclusion

• 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.

19
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 )

20
Next Steps

• Device Ontology
• Integrate with upper ontology SUMO/CYC
• User Profiles
• Likes / Interests
• Service Ontology
• Service description / High-level language
  (scripting)

21
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
