Event-based Middleware for Pervasive Computing- Foundations Concepts Design

Mobile applications running on personal devices like smartphones PDAs orlaptop computers create a fascinating market for many new mobile services.Mobile commerce location-based services multimedia messaging or mobilegaming are expected to constitute a main driving-force for technological advancementscreating a new source of revenue for infrastructure providersand developers. Based on what we observe today the logical next steps leadto integrated infrastructures and applications supporting pervasive computing.Whatever this future will look like the basic cornerstones will be: (i) highlynomadic users (ii) personalized devices running smart applications (iii) pervasivesmart infrastructures and (iv) efficient communication for end-to-endintegration of all building blocks.This book introduces the amazing world of pervasive computing leads stepby-step through the new design challenges for pervasive computing applicationsand identifies the key challenges for engineering middleware supportingpervasive applications. Based on the well-known publish/subscribe paradigmit demonstrates how middleware systems can be designed to explicitly makeuse of context of users and applications. It then shows how context informationcan be leveraged for optimizing the efficiency of communication insidea notification service.The book addresses developers of middleware mobile application designersas well as interested individuals who want to learn more about the challengesof next generation pervasive and mobile systems.
