Prototype Platforms for Distributed Agreements

We present a prototype application for coordinating distributed agreements in multi-parties negotiations, where participants can dynamically join ongoing negotiations and where participants know only those parties they have interacted with. Our prototype is tailored to Ad-Hoc network scenarios involving the assignment of tasks for a rescue team operating over disaster areas. Our application is based on asynchronous communication and it exploits the D2PC protocol for committing or aborting a negotiation. Parties have been developed both in Jocaml+Perl and Polyphonic C#. The implementation of the commit protocol allows components of both types to participate within the same negotiation.
