Electing a global mediator in a three-layer mediation architecture

摘要

The authors' ongoing research project is a system that mediates access to heterogeneous multi-media sources while considering the quality of service to clients. Several intermediate mediator components are involved in the delivery of data. One of the mediators is responsible for assuring the quality of presentation of the mediated information. In this paper, we present the algorithm used to elect this global-mediator.
