Motivation • Computing is going mobile, ubiquitous, service oriented • Mobile use means dynamic variation in user needs and available computing and communication resources • Applications must adapt to such changes in order to sustain availability, usability and usefulness Brussels September 27, 2005 Slide 2

Madam Objectives • Provide support for the development of applications that adapt dynamically to changes in context (at launch time and during use) Brussels September 27, 2005 Slide 3

Approach Architects, application developers develop - Application reference architecture Design Models - Notation extensions Application use & (UML profile) developers refine - Modeling tool I mplement - Transformation tool Components Types Application (MOFscript, based on EMF) & Plans components retrieves Distributed MADAM runtime - Middleware Application Adaptation models instance builds, Middleware builds & - context monitoring maintains adapts - context reasoning & uses provides monitors service to - adaptation reasoning & decision making Context - (re)configuration - application launch needs Distributed and initial adaptation computing noise position battery Mobile user infrastructue Brussels September 27, 2005 Slide 4
