From fundamental concepts and theories to implementation protocols and cutting-edge applications, the Handbook of Mobile Systems Applications and Services supplies a complete examination of the evolution of mobile services technologies. It examines service-oriented architecture (SOA) and explains why SOA and service oriented computing (SOC) will play key roles in the development of future mobile services. Investigating current service discovery frameworks, the book covers the basics of mobile services and applications developed in various contexts. The first section provides readers with the required background in mobile services architecture. Next, it details of middleware support for mobile services. The final section discusses security and applications of mobile services. Containing the contributions of leading researchers and academics from around the world, the book: Introduces a new location-based access control modelUnveils a simple, yet powerful enhancement that enables Web services to locally manage workflow dependencies and handle messages resulting from multiple workflowsExamines an event-based location aware query model that continuously aggregates data in specific areas around mobile sensors of interestAddresses the problem of location-based access control in the context of privacy protectionPresents a layered architecture of context-aware middleware Considers the development of assistive technology solutions for the blind or visually impairedDiscussing architecture for supporting multi-mode terminals in integrated heterogeneous wireless networks, this book addresses the network availability constraint to serve all mobile services originating from a single-user terminal. It examines QoS protocols and their enhancements in supporting user mobility. Analyzing mobile services security vulnerabilities, it details security design best practices that mobile service developers can use to improve the security of their mobile systems.

How do firms jointly develop open information infrastructures? To answer this question, this book draws on the results of a longitudinal research project covering the development of the pharmaceutical distribution industry in China from 2004 to 2012, focusing on the emergence and subsequent evolution of industry-wide information infrastructures. How do firms delimit areas of proprietary innovation in open innovation projects? How do firms coordinate, initiate, negotiate and implement the development of innovative infrastructures? How do processes and practices within firms enable and constrain such collective efforts? - This book provides answers to these questions and draws conclusions regarding the challenges and new capabilities that firms will need in a world in which participation in the building of open information infrastructures becomes a necessary task for commercial organizations.

Ad hoc and ubiquitous computing technologies have received extensive attention in both the academia and industry with the explosive growth of wireless communication devices. These technologies are beneficial for many applications, such as offering futuristic high bandwidth access for users, and are expected to offer more exciting and efficient services, anytime and anywhere. In order to satisfy these diverse applications, the design issues of various wireless networks such as ad hoc, sensor, and mesh networks are extremely complicated and there are a number of technique challenges that need to be explored, involving every layer of the OSI protocol stack.This book aims to provide a complete understanding of these networks by investigating the evolution of ad hoc, sensor, and mesh networking technologies from theoretic concept to implementation protocols, from fundamentals to real applications. It provides the necessary background material needed to go deeper into the subject and explore the research literature. The explanation in the book is therefore sufficiently detailed to serve as a comprehensive reference for students, instructors, researchers, engineers, and other professionals, building their understanding of these networks.
