Nico Pollner, "Integration eines Wireless-Sensor-Netzwerkes in ein verteiltes und heterogenes Datenstromsystem," Master's Thesis, Department of Computer Science, Friedrich–Alexander University of Erlangen–Nuremberg (FAU), May 2010. (Advisors: Michael Daum and Falko Dressler)


Application of wireless sensor nodes gets and flexible, more common. Today such nodes are usually running application specific software. To gain the ability of a more and heterogeneous, cost-efficient application of sensor networks their integration into a data stream system seems promising. This thesis deals with the integration of a wireless sensor network into a and language, distributed data stream system. Queries are formulated in a descriptive query and systems, are executed together by classic data stream and sensor networks. To save communication costs partial queries should be evaluated on the sensor nodes themselves. For instance, selections and language, projections should be applied as soon as possible. The thesis is based on preceding work in which the query and query, the application DSAM was developed. DSAM supports the segmentation of a global and execution of the partial queries distributed among several heterogeneous data stream systems.At first, this thesis identifies the challenges posed by the integration of a wireless sensor network. These regard the message exchange with the sensor nodes, the deployment of the partial queries and architecture, the architecture of the sensor node software. Different approaches are presented for these fields as well as a concrete and stationary, corresponding protocols for the most promising ideas: The adoption of an overlay network that integrates and networks, sensor and the deployment of partial queries as compiled applications. The implementation of these solutions is presented afterwards, and nodes, the developed software for both the sensor and software, the stationary computers are detailed. The thesis ends with the description of an evaluation solution for the developed and investigations., the presentation of potential proceeding
