Heute sind es Computer und Handys, die miteinander vernetzt sind und den Informationszugriff immer und überall ermöglichen. Schon bald aber lassen sich kleinste, billige und über Funk miteinander kommunizierende Prozessoren und Sensoren in fast beliebige Dinge einbauen. "Smarte" Alltagsgegenstände können dann ihre Umgebung erfassen, haben Zugriff auf beliebige Ressourcen im Internet und wissen, wo sie sind und wer in der Nähe ist. Wie aber leben wir in einer solchen total informatisierten und vernetzten Welt? In diesem Buch kommen Wissenschaftler zu Wort, die auf dem Gebiet des ubiquitous computing arbeiten. Sie erläutern das Potential der allumfassenden Informatisierung und diskutieren mögliche Anwendungen und Auswirkungen.

This book constitutes the refereed proceedings of the Second International Conference on Pervasive Computing, PERVASIVE 2004, held in Vienna, Austria in April 2004.The 26 revised full papers presented were carefully reviewed and selected from a total of 278 submissions. The papers are organized in topical sections on activity recognition, context computing, near body interfaces, software, sensors, security, architectures and systems, algorithms, and new interfaces.

Mit dem "Internet der Dinge" zeichnet sich ein fundamentaler Technik-Trend ab, dessen betriebswirtschaftliche Konsequenzen und Chancen hier erstmals erläutert werden. Das Buch stellt dabei nicht nur eine klare technologisch wie ökonomisch begründete Vision des Ubiquitous Computing dar, sondern beschreibt darüber hinaus in mehreren Fallstudien auch deren Umsetzung in die Unternehmenspraxis unterschiedlichster Branchen, skizziert die wichtigsten Technologien und leitet unmittelbar anwendbare Handlungsanleitungen ab. Es liefert eine fundierte, in sich geschlossene und übersichtlich dargestellte Analyse für Praktiker, Forscher und Studierende, die sich mit Gestaltung, Chancen und Risiken von RFID-Anwendungen und Ubiquitous-Computing-Szenarien auseinandersetzen.

This volume contains the proceedings of EWSN 2006, the third in a series of - ropean workshops on wireless sensor networks. The workshop took place at ETH Zurich from February 13 to 15, 2006. Its objective was to present, discuss, and explore the latest technical developments in the ?eld of wireless sensor networks, as well as potential future directions. Wireless sensor networks provide a bridge between traditional information systems and the physical world, with collections of wirelessly networked s- sor nodes being deployed in our physical environment to cooperatively monitor real-world phenomena, but also to control aspects of the physical world. In c- trast to traditional computing systems which are mostly decoupled from the real world,wirelesssensornetworksareinherentlyandcloselyintegratedwiththereal world, with data about the physical environment being captured and processed automatically, online, and in real time. This paradigmatic change comes with a number of conceptual and technical challenges involving a wide range of dis- plines in computer science and electrical engineering, but also material sciences, MEMS technology, and power engineering, thus making wireless sensornetworks a multidisciplinary area of research. This workshop series aims at providing a high-level scienti?c forum to implement the cross-disciplinary exchange of ideas andresultsthatisessentialforthistypeofresearcharea. WhilebasedinEurope, the workshop serves as a truly international forum with 40% of the submissions originating from Europe, 38% from Asia and Australia, 20% from the Americas, and2%fromAfrica. Wireless sensor networks has become an active and popular research area, which is witnessed by the 133 submissions we received from authors all over the world.TheProgramCommitteechose21papersforinclusionintheworkshop.

ThisvolumecontainstheproceedingsoftheSecondInternationalSymposium on Agent Systems and Applications and the Fourth International Symposium onMobile Agents.ASA/MA 2000tookplacein Zurich,Switzerland,atthe ETH (the Swiss Federal Institute of Technology) on September 13-15, 2000. In the age of information overload, agents have become an important p- gramming paradigm. Agents can act on behalf of users to collect, ?lter, and process information. They can act autonomously and react to changing en- ronments. Agents are deployed in di?erent settings, such as industrial control, Internet searching, personal assistance, network management, games, and many others. In our increasingly networked world, mobile code is another important p- grammingparadigm.Indistributed applicationsmobile code can improvespeed, ?exibility,structure,security,orthe ability to handle disconnection.Mobile code has been applied to mobile computing, wireless networks, active networks, m- ufacturing,networkmanagement,resourcediscovery,softwaredisseminationand con?guration, and many other situations. Mobile agents combine the features of agents and mobile-code technologies, and present their own set of challenges.Their use is increasingly explored by an expanding industry.

This book constitutes the refereed proceedings of the First International Conference on Pervasive Computing, Pervasive 2002, held in Zurich, Switzerland in August 2002. The 20 revised full papers presented together with an invited paper were carefully reviewed and selected from a total of 162 submissions. The papers are organized in topical sections on system design; applications; identification and authentication; models, platforms, and architectures; location and mobility; and device independence and content distribution.

Verteilte Algorithmen sind Verfahren, die dadurch charakterisiert sind, dass mehrere autonome Prozesse gleichzeitig Teile eines gemeinsamen Problems in kooperativer Weise bearbeiten und der dabei erforderliche Informationsaustausch ausschliesslich uber Nachrichten erfolgt. Derartige Algorithmen kommen im Rahmen verteilter Systeme zum Einsatz, bei denen kein gemeinsamer Speicher existiert und die Ubertragungs- und Bearbeitungsdauer von Nachrichten i.a. nicht vernachlassigt werden kann. Fur wichtige Grundprobleme, zu denen das Election-Problem, das Schnappschussproblem und das Terminierungsproblem gehoren, werden in diesem Buch verschiedene Losungsalgorithmen angegeben und miteinander verglichen. Die Bewertung der Algorithmen umfasst analytische und empirische Untersuchungen sowie eine Diskussion der qualitativen Eigenschaften verschiedener Varianten. Neben grundsatzlichen Aspekten, etwa der Bedeutung des Zeitbegriffs in verteilten Systemen, werden einige typische Methoden und Techniken vorgestellt, die fur die Konstruktion und Analyse verteilter Algorithmen, aber auch fur die Programmierung verteilter oder paralleler Systeme von praktischer Bedeutung sind.

This volume is based on the workshop "Unifying Theory and Practice in Distributed Systems" held in Schlob Dagstuhl, Germany in September 1994. During the past 20 years, a substantial theoretical and practical base has evolved in the area of distributed computing. However, this work has been done by largely disjoint communities of researchers; this workshop brought together established experts from both worlds. The volume contains 17 full papers refereed and revised after the workshop so that they reflect original research enriched by insights gained through discussions at the workshop. Among the issues treated are paradigms and concepts, fundamental algorithms and principles, fault-tolerance, real-time, system structures, large case aspects and others.

ThisvolumecontainstheproceedingsoftheInternetofThings(IOT)Conference 2008, the ?rst international conference of its kind. The conference took place in Zurich,Switzerland, March26–28,2008. The term ‘Internet of Things’ hascome to describe a number of technologies and researchdisciplines that enable the - ternet to reach out into the real world of physical objects. Technologies such as RFID, short-range wireless communications, real-time localization, and sensor networks are becoming increasingly common, bringing the ‘Internet of Things’ into industrial, commercial, and domestic use. IOT 2008 brought together le- ing researchersand practitioners, from both academia and industry, to facilitate the sharing of ideas, applications, and research results. IOT 2008 attracted 92 high-quality submissions, from which the technical program committee accepted 23 papers, resulting in a competitive 25% acc- tance rate. In total, there were over 250 individual authors from 23 countries, representing both academic and industrial organizations. Papers were selected solely on the quality of their blind peer reviews. We were fortunate to draw on the combined experience of our 59 program committee members, coming from the most prestigious universities and research labs in Europe, North America, Asia, and Australia. Program committee members were aided by no less than 63 external reviewers in this rigorous process, in which each committee member wrote about 6 reviews. The total of 336 entered reviews resulted in an average of 3. 7 reviews per paper, or slightly more than 1000 words of feedback for each paper submitted.
