Ionescu, Mihail and Marsic, Ivan (2003): Tree-Based Concurrency Control in Distributed Groupware. In Computer Supported Cooperative Work, 12 (3) pp. 329-350

“We present a novel algorithm, called dARB, for solving the concurrency control problem in distributed collaborative applications. The main issue of concurrency control is resolving the conflicts resulting from simultaneous actions of multiple users. The algorithm reduces the need for manual conflict resolution by using a distributed arbitration scheme. The main advantages of our approach are the simplicity of use and good responsiveness, as there are no lock mechanisms. Our algorithm requires the applications to use a tree as the internal data structure. This makes it application independent and suitable for general collaborative applications. The tree requirement is reasonable since many new applications use XML (extensible Markup Language) for data representation and exchange, and parsing XML documents results in tree structures. Example applications of the algorithm, a group text editor and a collaborative 3D virtual environment called cWorld, are implemented and evaluated in the DISCIPLE collaboration framework. We also introduce awareness widgets that users avoid generating the conflicting events and help in manual conflict resolution.”

Fontoura, Marcus, Ionescu, Mihail and Minsky, Naftaly (2002): Law-governed peer-to-peer auctions. In: Proceedings of the 2002 International Conference on the World Wide Web 2002. pp. 109-116. Available online

“This paper proposes a flexible architecture for the creation of Internet auctions. It allows the custom definition of the auction parameters, and provides a decentralized control of the auction process. Auction policies are defined as laws in the Law Governed Interaction (LGI) paradigm. Each of these laws specifies not only the auction algorithm itself (e.g. open-cry, dutch, etc.) but also how to handle the other parameters usually involved in the online auctions, such as certification, auditioning, and treatment of complaints. LGI is used to enforce the rules established in the auction policy within the agents involved in the process. After the agents find out about the actions, they interact in a peer-to-peer communication protocol, reducing the role of the centralized auction room to an advertising registry, and taking profit of the distributed nature of the Internet to conduct the auction. The paper presents an example of an auction law, illustrating the use of the proposed architecture.”
