The aim of this work is to provide a robust way for peers with heterogeneous data sources to exchange information in an unreliable network. We address this problem in two ways. Firstly, we define a set ofapplication-layer data exchange protocols to facilitate the discovery of and the communication between peers. Secondly, we provide a query processing component with acache-driven query processor that allows peers on the network to cachequeries and their results on demand. The data caches are used togive partial or complete answers to a query if the original data sources are unavailable.
