Toward a Flexible Data Management Middleware for Wireless Sensor Networks

In this paper we present the research activity we are carrying out in the "Mobile Semantic Self-Organizing Wireless Sensor Networks" Project at the Department of Information Engineering of the University of Modena and Reggio Emilia. In this context, the main aim of our research is to study solutions for the flexible querying of distributed data collected by heterogeneous devices providing measurement readings. To this end, we propose a middleware for wireless sensor networks which is able to autonomously configure the communication and the operations required to each device in order to reduce energy and temporal costs.
