Abstract

Early sensor network data access systems were built upon the the idea of data-centric routing. Data-centricity allows robust and energy-efficient communication by abstracting the physical location of data. In this chapter, we introduce a complementary idea called data-centric storage. Data-centric storage provides efficient rendezvous between the producer of a data item, and its consumer. The primitives underlying data-centric storage can be used to construct different distributed data structures for efficiently answering a variety of queries.
