Description
Summary:In this paper, we present DSAM, a data stream application manager. DSAM supports the deployment of global queries to distributed and heterogeneous sensor nodes and stream processing systems (SPSs). We provide a graph-based global query language DSAM-AQL. The abstract query language (AQL) is a declarative streamoriented query language that abstracts from topology and distribution of wireless sensor networks (WSNs) and the heterogeneity of their nodes. Query processing and distribution is supported by a central catalog that manages all stream schemas, nodes, (initial) topology, SPSs, queries, performance characteristics of both network connections and nodes, and expressiveness of nodes' supported query languages and query definitions. DSAM supports query partitioning, query mapping, deployment, and monitoring of distributed data stream applications. We focus on DSAM's infrastructure and the procedures of deployment of global queries.
