CONTEXT-AWARE PARADIGM FOR A PERVASIVE COMPUTING ENVIRONMENT (CAPP)

ABSTRACT Pervasive Computing integrates numerous, casually accessible and inexpensive mobile devices with traditional distributed systems. The foremost issue of pervasive computing is Context-Awareness. Context-Aware Paradigm for Pervasive Computing Environments (CAPP) is a Service Oriented Architecture (SOA) that enhances smart service discovery in a pervasive environment. Objective of CAPP is to deliver the best service available, among a pool of similar services, to the mobile user. The system gathers the low-level service and user contexts and interprets both these contexts into the high-level ‘Who’, ‘What’, ‘Where’ and ‘When’ contexts. The interpreted high-level context is then used to discover the best available service for the user. The effectiveness of CAPP is measured in terms of success and failures where success is the systems ability to select an appropriate service from a pool of similar service to the user, based on the contexts. The projected success rate of the test cases is 89%.
