An Overlay Network for Integration of WSNs in Federated Stream-Processing Environments
This paper presents an approach for seamless integration of hosts in heterogeneous networks in the context of data-stream processing. The integration of multiple heterogeneous hosts from the sensor-node level up to the level of high-performance workstations is one of the most promising concepts for extensive and efficient analysis of streaming data. For controlling such a network, communication between hosts is needed, e. g., to initiate stream processing, to configure queries, and to transmit streams. One of the key challenges is global addressing and transparent yet efficient data exchange despite diverse, differently capable networks involved.
