Overview

Fast growth of technologies and miniaturization of devices and sensors has led embedding computational capabilities ubiquitous, which impact all aspects of our everyday life. Ubiquitous Computing is a physical reality, which ensures the presence of computers and information everywhere. The ubiquitous presence of computers and information becomes more meaningful when they are user context aware in nature. This book investigates two important research issues of Ubiquitous Computing: Modeling user Context and Conflict Resolution.In this research a novel approach to model user context is introduced. The conflict resolving algorithms have been designed by integrating the contextual parameters like social, personal, temporal, activity, mood, ratings and social agendas with AI tools like rule base, fuzzy Bayesian probability and rough set theory. The usage of the proposed context model and conflict resolving algorithms is demonstrated in developing applications like Context Aware TV and Context Aware Mobile.
