Pervasive computing environments

Pervasive Computing Environments

  • Users are surrounded with ubiquitous communication and information technology.

  • Unobtrusive services assist users in their daily lives.

  • Context awareness has emerged as a central element in pervasive computing.

  • Notification services are key applications.


Requirements for a user notification service

Requirements for a User Notification Service

  • Current middleware provides unified ways to subscribe to and manage context data.

  • Key Issues:

    • A flexible, efficient and convenient mechanism to allows user-applications to specify what changes in the environment should be notified to them.

    • Tailor the user notification to the user’s context.


Ans a rule based user notification service

ANS - A Rule-Based User Notification Service

  • A rule-based approach relieves user-application developers from regarding and logically combining multiple context sources in their application.

  • ANS provides an expressive and simple language that enables users (application developers) to state what they are interested in.

  • ANS provides notifications based on the user’s preferences and their current context

ANS Rule Language

  • The focus of the rule language is on the following qualities:

    • Expressive power: the language permits the specification of complex event relations. It allows the use of logical connectives (e.g., AND, OR, NOT) on conditions to build compound conditions.

    • Convenient use for application developers: It provides high-level constructs that facilitate event compositions.

    • Extensibility: The language allows the addition of new predicates to accommodate events being defined on demand.

ANS Rule Language Examples

  • Notify Jerry if his computer is online when he leaves his room.

  • Upon leaveRoom (Jerry, Room101)

  • When IsOnline (Jerry)

  • Do Notify (Jerry, “Jerry, your computer has been left on”)

  • The Awareness and Notification Service is part of the middleware EU-project AMIGO. A first version of the service is currently being deployed in the AMIGO Ambient Intelligence Environments.
