[Apologies for multiple copies of this message] Call for Papers: Fifth Workshop on Large Scale Distributed Virtual Environments, LSDVE 2017, <http://pages.di.unipi.it/ricci/LSDVE17/LSDVE17.html> in conjunction of EUROPAR 2017 <http://europar2017.usc.es/> August 2017, Santiago de Compostela, (Spain) Proceedings will be published by Springer Lecture Notes in Computer Science. Extended versions of the accepted papers will be published in a special issue (pending). IMPORTANT DATES Paper submission deadline: 5 May 2017 Notification of Acceptance: 16 June 2017 Workshop Date: August 2017 Submission of Camera Ready papers: 3 October 2017 Objectives of the Workshop: The recent advances in networking have determined an increasing use of information technology to support distributed networked cooperative applications. Several novel applications have emerged in this area: social networks, distributed payment systems, connected devices, collaboration systems, and many other ones. These applications may greatly benefit from the support of different kinds of platforms, both cloud and peer to peer. An interesting technology recently adopted to handle cryptocurrencies (such as bitcoin) is the block-chain technology, that has now taken the more general role to handle several distributed applications. Furthermore, the analysis and validation of the huge amount of content generated by these applications asks for big data analysis and processing techniques. This workshop aims to provide a venue for researchers to present and discuss important aspects of large scale networked collaborative applications and of the platforms supporting them. The definition of these applications requires to afford several challenges, like the design of user interfaces, coordination protocols, and proper middle-ware and architectures. The track's aim is to investigate open challenges for such applications, related to both the applications design and to the definition of proper supports. Some important challenges are, for instance, adaptation of the classical block-chain technology to support collaborative applications, protocols design, distributed consensus algorithms, privacy and security issues. The workshop will both present assessment of current state and introduce further directions. Topics of interest include but are not limited to: - Distributed Large Scale Collaborative Environments (LSCE) and applications - Online Social Networks - Distributed financial transactions systems - Connected devices tracking in distributed systems - Distributed Virtual Environments - Platforms for collaborative applications - Block-chain technology to support LSCE - Distributed Consensus - General purpose distributed auditing through block-chains - Cloud platforms for LSCE - P2P platforms - Distributed cloud storage systems - Big Data processing for LSCE - Security and Privacy in LSCE Program Commettee (to be completed) Michele Amoretti, University of Parma, Italy Emanuele Carlini, ISTI CNR, Pisa, Italy Giuseppe Di Battista, University of Roma 3, Italy Kalman Graffi, Univerity of Dusseldorf, Germany Barbara Guidi, University of Pisa, Italy Alexandru Iosup, TU Delft, Holland Jose Antonio Fernandes de Macedo, Federal University of Cearà, Brasil Andrea Marino, University of Pisa, Italy Fabrizio Marozzo, University of Calabria, Italy Pietro Michiardi, EURECOM, France Alberto Montresor, University of Trento, Italy Dana Petcu, West University of Timisoara, Romania Radu Prodan, Institute of Computer Science, Innsbruck, Austria Laura Ricci, University of Pisa, Pisa, Italy We invite original papers previously unpublished.
