چکیده
This chapter reviews a number of emerging topics pertaining to a data-centric view of wireless sensor networks. These topics include data-driven routing, tracking mobile objects, constructing and maintaining reporting trees, dynamic evolution of a monitoring region for moving targets (mobicast), disseminating monitoring tasks, data gathering, receiving reports from a particular area of interest, and sending information and task assignment from a sink to all the sensors inside a geographic region (geocasting). The chapter also discusses various other issues, including sensor training options, data aggregation, data storage, as well as design guidelines for data aggregation and clustering, and rate-based data propagation in wireless sensor networks.
