06431 – Working Group Summary — Atomicity in Mobile Networks — Dagstuhl Seminar Scalable Data Management in Evolving Networks (2009)

Joos-hendrik Böse, Stefan Böttcher, Panos Kypros Chrysanthis, Le Gruenwald, Anirban Mondal, Sebastian Obermeier, ...

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...

P2P, Ad Hoc and Sensor Networks – All the Different or All the Same? Working Group Summary (2009)

Peter A. Boncz, Angela Bonifati, Joos-hendrik Böse, Stefan Böttcher, Fu Berlin, ...

Summary. 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...

A Failure Tolerating Atomic Commit Protocol for Mobile Environments (2009)

Stefan Böttcher, Le Gruenwald, Sebastian Obermeier

In traditional fixed-wired networks, standard protocols like 2-Phase-Commit are used to guarantee atomicity for distributed transactions. However, within mobile networks, a higher probability of...

for Guaranteeing Anonymity of Distrustful Participants (2008)

Stefan Böttcher, Sebastian Obermeier

Abstract — The computation of the union operator for different distributed datasets involves two challenges when participants are curious and can even act malicious: guaranteeing anonymity and...

S.: Reducing sub-transaction aborts and blocking time within atomic commit protocols (2008)

Stefan Böttcher, Le Gruenwald, Sebastian Obermeier

Abstract. Composed Web service transactions executed in distributed networks often require an atomic execution. Guaranteeing atomicity in mobile networks involves a lot more challenges than in...

An Atomic Web-Service Transaction Protocol for Mobile Environments (2008)

Stefan Böttcher, Le Gruenwald, Sebastian Obermeier

Abstract. Atomicity is a widely required property of Web service transactions that are executed in distributed networks. Compared to fixedwired networks, atomicity in mobile networks is much more...

Abstract (2008)

Joos-hendrik Böse, Sebastian Obermeier, Stefan Böttcher

While traditional fixed-wired network protocols like 2-Phase-Commit guarantee atomicity, we cannot use them in mobile low bandwidth networks where network partitioning, node failure, and message loss...

06431 Working Group Summary: Atomicity in Mobile Networks (2007)

Obermeier, Sebastian, Böse, Joos-Hendrik, Böttcher, Stefan, Chrysanthis, Panos Kypros, Delis, Alex, Gruenwald, Le, ...

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...

The design of pamanet the paderborn mobile ad-hoc network (2004)

Peter Bleckmann, Stefan Böttcher, Eduardas Cesnavicius, André Francisco, Tim Daniel, Hollerung Birger, ...

Wireless connectivity is state of the art for local area networks. Currently, most W-LAN networks rely on a centralized design with access points routing all inner and outbound traffic. These access...
