    Introduction: Integrated Computer-Aided Engineering
    (Birmingham: IOS Press International, 2013)
    Kropf, Peter 
    This special issue is based on the 15th InternationalConference on Computer Supported Cooperative Workin Design (CSCWD 2011) held in Lausanne, Switzer-land, on June 8–11, 2011. CSCWD is a series of annualinternational conferences (http://www.cscwd.org/) or-ganized by the IEEE SMC Technical Committee onComputer Supported Cooperative Work in Design toprovide a forum for researchers and practitioners in-volved in different but related domains to confront re-search results and discuss key problems in the designof complex artifacts. The scope includes the researchand developmentfieldsof collaboration technologiesand their applications to the design of processes, prod-ucts, systems, and services in industries and societies. From about 130 papers presented in technical ses-sions at the conference, authors of the twenty six pa-pers considered to be the most innovative and originalin terms of collaboration technologies and engineeringapplications were invited to submit “substantiallyex-tended and updated manuscripts with additional origi-nal computational materials based on their most recentresearch”for possible publication in this issue. It wasalso noted “theoverlap between the new submissionand the paper published in the conference proceed-ings should not be more than 50%.”Each submittedextended manuscript was reviewed subsequently by 4to 7 reviewers using the journal review form. The sixmanuscripts included in this issue are those that passedthrough two rounds of the journal’s rigorous review process successfully.

    Many innovative P2P algorithms designed for mobile ad-hoc networks (MANETs) have been designed to scale smoothly when handling a very large number of nodes and transmissions. To cope with the complexity of software development for large-scale MANETs, simulations are widely used instead because hardware implementations are too costly. Simulations are very well suited to testing and evaluating concepts, but when implementing algorithms for testing on target systems, unexpected problems can often surface. Thus, once simulations have provided satisfactory results, emulation is a more desirable approach for detecting and handling unexpected behavior before committing to large-scale deployment. In particular, given that large P2P testbeds require a large number of devices spread over a prohibitive space and are limited by complex programming models, the authors are featuring a Java-based emulator called Freemote. To demonstrate some of the practical advantages of combining simulation and emulation, Freemote makes it possible to integrate real and emulated nodes, and the real nodes (JMotes) run exactly the same Java programs as emulated nodes. Since the JMotes are still not very widely used, the Freemote emulator and JMotes have been designed to be compatible with the more popular Berkeley’s motes. Furthermore, remarkable visualization and development tools have been implemented to undertake large-scale emulation of ad-hoc algorithms, featuring a high level of realism. Freemote has been tested in emulations for up to 10,000 nodes, distributed over ten computers (refer to a preceding chapter of this book “P2P Information Lookup, Collection and Distribution in Mobile Ad-Hoc Network” for a test application running DHT algorithms). In this chapter, the authors present the Freemote platform along with the results of a brief comparison of emulation and simulation experiments.

    We describe the interaction and relation between entities in distributed systems, as proposed in the Web Operating System (WOS). Every entity in the system is a versioned object which depends on its current context, which itself is programmable and can be effected by the objects circulating within it. These entities interact through mechanisms of requests/answers and negotiations. Those who exhibit functional and behavioral affinities may dynamically associate themselves to form communities. This positional paper states the basic ideas of the notion of communities in distributed systems.
