Introducing the XVSM Micro-Room Framework
Studium: Masterstudium Software Engineering & Internet Computing

Nowadays, all popular online social networks in the World Wide Web are based
on a client-server architecture. This leads to severe privacy issues as the
provider of the online social network holds all data and could easily misuse it.
Other contributions already showed how to resolve this problem by decentralizing
the data with a peer-to-peer architecture. Yet these solutions have their
own drawbacks, e.g. many complex technologies, bad extensibility or a lack of
important privacy and security features. A cause for these drawbacks is that no
satisfying high-level peer-to-peer frameworks exist, allowing users to develop
complex peer-to-peer applications in an easy way. Available frameworks are
rather low-level, concentrating on the communication layer. Therefore, all of
the peer-to-peer online social networks analysed have been created more or
less from scratch. To overcome this issue, we introduce the XVSM Micro-Room
Framework which focuses on ensuring those aspects, not covered sufficiently
by the existing peer-to-peer online social networks. This framework allows to
create peer-to-peer applications based on configurable, shared data rooms. We
then use the XVSM Micro-Room Framework for creating a proof of concept
peer-to-peer online social network settled in an e-learning environment. By
comparing our solutions (both the XVSM Micro-Room Framework and the
generated peer-to-peer online social network) with the analysed related work,
we demonstrate the benefits of our solutions regarding functionality, simplicity,
extensibility, privacy and security. Finally, several performance benchmarks
show the practicability of the XVSM Micro-Room Framework even in heavy-load
scenarios.

Relaxed non-blocking Distributed Transactions for the eXtensible Virtual
Shared Memory
Studium: Masterstudium Technische Informatik
BetreuerIn: Ao.Univ.Prof. Dr. Eva Kühn
In the development of distributed applications, especially communication and
coordination are complex tasks. Therefore developers are using middleware
technologies which are hiding the complexity and providing enterprise features
like transactions out-of-the box. Especially middlewares which are following the
space-based computing (SBC) paradigm are often used for coordination tasks.
