06431 Summary – Scalable Data Management in Evolving Networks"

Authors: Stefan Böttcher, Le Gruenwald, Pedro Jose Marrón, and Evaggelia Pitoura

Abstract
Network technologies like mobile ad-hoc networks, peer-to-peer systems, and sensor networks are getting increasingly popular, but come up with new challenges to scalable data management because data management techniques developed for fixed-wired networks that usually depend on reliable and stable networks can not directly be used. The goal of this Dagstuhl Seminar was to identify common challenges in these popular network technologies problems, and to get a better understanding of the generality and applicability of solutions to the major problems in scalable data management in these areas.

06431 Working Group Summary: Atomicity in Mobile Networks

Authors: Sebastian Obermeier, Joos-Hendrik Böse, Stefan Böttcher, Panos Kypros Chrysanthis, Alex Delis, Le Gruenwald, Anirban Mondal, Aris Ouksel, George Samaras, and Stratis Viglas

Abstract
We introduce different mobile network applications and show to which degree the concept of database transactions is required within the applications. We show properties of transaction processing and explain which properties are important for each of the mobile applications. Furthermore, we discuss open questions regarding transaction processing in mobile networks and identify open problems for further research.

06431 Working Group Summary: P2P, Ad Hoc and Sensor Networks – All the Different or All the Same?

Authors: Peter A. Boncz, Angela Bonifati, Joos-Hendrik Böse, Stefan Böttcher, Panos Kypros Chrysanthis, Le Gruenwald, Arantza Illarramendi, Peter Janacik, Birgitta König-Ries, Wolfgang May, Anirban Mondal, Sebastian Obermeier, Aris Ouksel, and George Samaras

Abstract
Currently, data management technologies are in the process of finding their way into evolving networks, i.e. P2P, ad hoc and wireless sensor networks. We examine the properties, differences and commonalities of the different types of evolving networks, in order to enable the development of adequate technologies suiting their characteristics. We start with presenting definitions for the different network types, before arranging them in a network hierarchy, to gain a clear view of the area. Then, we analyze and compare the example applications for each of the types using different design dimensions. Based on this work, we finally present a comparison of P2P, ad hoc and wireless sensor networks.

P2P XQuery and the StreetTiVo application

Authors: Peter A. Boncz and Yi Zhang

Abstract
MonetDB/XQuery* is a fully functional publicly available XML DBMS that has been extended with distributed and P2P data management functionality. Our (minimal) XQuery language extension XRPC adds the concept of RPC to XQuery, and we outlined our approach to include the services offered by diverse P2P network structures (such as DHTs), in a way that avoids any further intrusion in the XQuery language and semantics. We also discussed the StreetTiVo application were mxq is being used for data management in a large P2P environment. new construct called XRPC.

Secure Multi-Party Data Management

Authors: Stefan Böttcher

Abstract
As data and information is stored, combined and accessed almost everywhere, in-formation security and privacy becomes increasingly important to companies that offer access to data. In comparison to network and hardware security that often focus on the protection of network or hardware from attackers from the outside, information security involves protection of certain information from users that have at least some access rights "inside" an information system. One key challenge in information secu-rity and privacy is to meet two contrary goals at the same time, i.e. to allow users to run applications which access the data that they need, but to prevent the same users from being able to infer sensitive information from the results returned by the appli-cation. While cryptography may be used as a supporting technology, the focus of our re-search at the University of Paderborn is to solve problems of information security and privacy. Our research involves different aspects of information security and privacy, e.g. access control, policies, key management, role management, inference control, detection of privacy leaks, sovereign information sharing and anonymous union com-putation. Although there are many great contributions to these problems by other groups in the community, within this paper, we focus on the research contributions by our group in Paderborn.

Transactions on replicated data in Mobile Ad Hoc Nets - and some further issues of large scalable networks

Authors: Heinz Schweppe

Abstract
In the Coco/Da project1 data centric middleware functions for Mobile Ad Hoc Nets have been investigated and developed. Transactional support2 and data replication are important functions of traditional data management systems. Using a volatile communication infrastructure, replication plays an even more important role than in fixed wired systems in order to increase availability of data. Keeping replica consistent, however, is more involved with unreliable communication.
