In that domain, due to miniaturization, reduced costs of electronic components and advanced information technologies, de- velopers are now off ered a wide range of practical opportunities to design, develop and deploy thousands of the coin-sized sensors and mechanical devices at multiple locations. Originally proposed by Mark D. Weiser in 1988, the concept of Ubiquitous computing may be considered as an evolutionary development of traditional computational methods and platforms. However, ubicomp enables real-time global sensing, context-aware informational retrieval, multi-modal interaction with the user and enhanced visual- ization capabilities. In eff ect, ubiquitous computing environments give extremely new and futuristic abilities to look at and interact with in our habitat at any time and from anywhere. Unforeseen ability to fuse rich diversity of information retrieval, processing and access methods available in ubiquitous computing environments, practically invisible devices and tight connectivity of distributed components raise many foundational, technological and engineering issues which were not even known prior to the third, ubicomp, wave of computing. Detailed cross-disciplinary coverage of those issues is really needed today for further progress and widening of application domains. This book collects twelve original works of researchers from eleven countries, which represent diff erent aspects of cu ing-edge research and application of Ubiquitous computing. The submissions are clustered into four sections: • Foundations • Security and Privacy • Integration and Middleware • Practical Applications Section Foundations is opened by the work of Mauro Marcelo Ma os where the concept of Knowledge-based Operating System (KBOS) is discussed. KBOS has ability of knowing how to perform tasks and how to self-adapt to the fl uctuations of resource X Preface availability when interacting with the surrounding environment. Studies of ubicomp foundations are continued by Ren-Song Ko who presents an original concept of mu- tual assistant networks (MANs) which combines social networks with wireless sensor networks, and provides an infrastructure for new location-aware social network applications, in which people may share the local and timely information that cannot be obtained on time from the Internet. Uncertainty and error handling in the case of the invisibility of the devices and lacking of user’s awareness is studied by Marie-Luce Bourguet. For resolving that problem the author off ers exploiting users’ correct men- tal models of the devices and data properties. Foundational technologies for content adaptation in Ubiquitous computing are considered by Wanderley Lopes de Souza1, Antonio Francisco do Prado, Marcos Forte and Carlos Eduardo Cirilo. In their work the authors describe the Internet Content Adaptation Framework (ICAF), and suggest to apply ontologies for content adaptation. Mianxiong Dong, Long Zheng, Kaoru Ota, Song Guo, and Minyi Guo shed light on and study shadows of caching mechanisms for improving communication in Ubiquitous computing environment. They discuss the concept of Ubiquitous Multi-Processor (UMP) and off er an optimized algorithm for resource allocation to a processing node, which can improve the overall performance of the UMP system. Extremely important and challenging issues of security and privacy in Ubiquitous computing environments are considered in three consecutive works of the second Sec- tion. Hyun-Seok Kim, Jin-Young Choi, and Sin-Jae Lee propose comprehensive Secu- rity Analysis of the RFID Authentication Protocol using model checking formalism of Failure Divergence Refi nement (FDR). Based on the results of model checking authors reconfi rm the existence of known security fl aws and propose new schemes for secure RFID communication. Vivian C. Kalempa, Rodrigo Campiolo, Lucas Guardalben, Uri- an K. Bardemaker, and João Bosco M. Sobral explore the challenges to ensuring privacy in ubiquitous computing environments and propose to extend a metamodel of such environments to the aspects provacy. Section Integration and Middleware is focused on the problems of interoperability in the joint context of ubiquitous computing environment, existing IT-infrastructure and people society. In their work, Nicolas Ferry, Vincent Hourdin, Stéphane Laviro e, Gaëtan Rey, Michel Riveill and Jean-Yves Tigli propose WComp, which is a middleware for ubiquitous computing capable of managing the dynamicity and heteroge- neity of entities in the so ware infrastructure. The proposed middleware solution is built in accordance with the principles of Web Service Oriented Architecture for De- vice (WSOAD). Habib Abdulrab, Eduard Babkin and Oleg Kozyrev describe semantically enriched integration framework for ubiquitous computing environment, which is called Ontology Mediator. The last section of the application of ubicomp in practical se ings starts with the work of R. Francese, I. Passero & Genoveff a Tortora. The authors discuss current challenges for mobile location-based pervasive content sharing applications. Interesting factual information and observations are presented by Dewi Agushinta R. , Tb.
