Our distributed mediation architecture employs a layered framework of presence, integration, and homogenization mediators. In order to find a mediation path from a client request to data sources, a Distributed Hash Table (DHT) algorithm is deployed in the integration layer. A designated global-mediator in the integration layer initiates the keyword based matching decomposition of the request with the used of the DHT. It generates an Integrated Data Structure Graph (IDSG), creates association and dependence relations between nodes in the IDSG, and then it generates a Global IDSG (GIDSG). GIDSG is used to stream data from the mediators in the homogenization layer where they connect to the data sources. The architecture is dynamic, scalable and does not have any central point of failure. In this paper we present our research on the use of the GIDSG for the integration of data in our three-layer mediation architecture.
