Data‐Centric Protocols for Wireless Sensor Networks
Ivan Stojmenović, Stephan Olariu · 2005
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 monitoring region for moving targets (mobicast), disseminating monitoring tasks, data gathering, receiving reports from particular area of interest, and sending information and task assignment from 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.
