    A generic and modular accounting and charging system for peer-to-peer applications
    (Kommunikation in Verteilten Systemen (KiVS), 2005) Hausheer, David; Gerke, Jan; Stiller, Burkhard
    Accountability is one of the keys to success for emerging P2P systems. In the absence of appropriate accounting and charging mechanisms, P2P applications may suffer from free-riders which benefit from other peers without contributing themselves. This paper describes a new Accounting and Charging system for P2P applications which separates generic accounting and charging functionality from individual underlying accounting mechanisms. The presented approach enables the design and implementation of different accounting schemes, independently from core accounting functionality. The approach has been implemented and successfully used with several accounting schemes in different P2P applications.

    A Peer-to-peer Purchase and Rental Smart Contract-based Application (PuRSCA)
    (it - Information Technology: Vol. 60, No. 5-6, 2018) Niya, Sina Rafati; Schüpfer, Florian; Bocek, Thomas; Stiller, Burkhard
    This work introduces the design and implementation of an Android-based Peer-to-peer Purchase and Rental Application termed PuRSCA, which leverages Smart Contracts (SC) and the Ethereum public blockchain (BC). As a Device-to-device (D2D) communication protocol, WiFi-Direct is chosen to enable the P2P data transmission between two parties. This work results in a cost-efficient, secure, SC-based, P2P, and Decentralized application (Dapp). Evaluations on performance of this Dapp is specified in terms of its D2D deployment, transaction costs, scalability, security, and privacy.

    Soability – A Model for the Strategic Evaluation of an IT Environment’s Ability to Support a Service-Oriented Architecture
    (Informatik 2007 – Informatik trifft Logistik – Band 1, 2007) Krähenbühl, Alexander; Stiller, Burkhard
    This document presents the Soability model, which assesses on a strategic level how well an IT environment is able to support an SOA based on Web Services. The model is designed to support the answering of typical questions that decision makers in companies face. By so doing the model addresses a lack of methodological support for stakeholders who need to plan an SOA holistically.
