Oscar Ardaiz Michele Catalano Pablo Chacin Isaac Chao Juan Carlos Cruellas Felix Freitag Manuel Medina Leandro Navarro Miguel Valero Liviu Joita Omer F. Rana Björn Schnizler Torsten Eymann

In this paper a performance measuring infrastructure,developed for the prototype and simulator, concering the experiment configuration, data measurement, and data collection, is presented. A corresponding performance evaluation framework is defined to obtain the metrics from the measured data. Initial experiments were carried out to test the developed prototype, simulator and the performance measuring infrastructure.

Oscar Ardaiz Pablo Chacin Isaac Chao Felix Freitag Leandro Navarro Liviu Joita Omer F. Rana Werner Streitberger Sebastian Hudert Torsten Eymann

In this report the progress of developing the proof-of-concept application in the CATNETS project is presented. Hence the development of the necessary performance measuring components as well as a distributed application to execute on economic-enhanced Grid/P2P platforms and middleware integration are described.

A Survey on Reputation Systems for Artificial Societies (2009)

Tina Balke Stefan König Torsten Eymann

The Internet has caused a revolution in trading. Especially cheap items are now easy to buy and sell on the Internet. As a consequence, sellers nowadays offer a wide range of products on the web, creating an abundance of choice for consumers. Consumers have the opportunity to browse on different auction sites for the item they really want. Along with this success story, however, came the stories of people being cheated by fraudulent online sellers. These frauds cover a range from not delivering what has been promised, the overrating of a product´s condition, to deliberate acts of theft. They are a result of so-called asymmetric information. Trust and reputation mechanisms are intended to address this asymmetric information distribution. This article surveys the most common trust and reputation systems.

Performance Evaluation - Annual Report Year 3 (2007)

Georg Buss Nils Parasie Daniel Veit Michele Catalano Pablo Chacin Isaac Chao Felix Freitag Leandro Navarro Omer F. Rana Liviu Joita Björn Schnizler Werner Streitberger Torsten Eymann

This report describes the work done and results obtained in third year of the CATNETS project. Experiments carried out with the different configurations of the prototype are reported and simulation results are evaluated with the CATNETS metrics framework. The applicability of the Catallactic approach as market model for service and resource allocation in application layer networks is assessed based on the results and experience gained both from the prototype development and simulations.

Simulator Development - Annual Report Year 2 (2006)

Gaetano Calabrese Björn Schnizler Werner Streitberger Torsten Eymann Floriano Zini

In this paper the simulation environment for the CATNETS project is defined further. The chosen simulator is adopted in terms of new features an architecture changes in order to provide a valid simulation environment for Application Layer Network scenarios. Furthermore the requirements for a scenario generator and the needed configuration mechanisms for the actual simulation runs are introduced.
