ABSTRACT
This chapter discusses most of the relevant Data-Centric Storage (DCS) studies in the literature and classifies them into two major routing categories: Point-to-point routing and routing based on tree structures. It provides a comparative table highlighting the salient features of each DCS mechanism. In providing data storage and search services for sensed events, a data storage scheme in a Wireless Sensor Networks (WSN) faces many challenges. Range query is another challenge for the DCS scheme. Due to the imprecise behavior of sensor hardware and the variation of environmental parameters, the similarity search problem in WSNs has received tremendous attention. Based on the basic data stored in sensors, DCS networks can facilitate data aggregation in a fully distributed way. Multireplication reduces the data loss that happens due to node failure or movement of data from one rendezvous zone to another. Furthermore, multireplication may facilitate data fusion and aggregation.
