Location Privacy Preservation in Database-DrivenWireless Cognitive Networks

Abstract

In this paper, we recommend new vicinity privatenesskeeping schemes for database-driven cognitive radio networks(CRNs) that guard secondary customers’ (SUs) region privatenesseven as allowing them to study spectrum availability of theirlocation. Our schemes harness probabilistic set membership recordsstructures to make the most the based nature of spectrum databases(DBs) and SUs’ queries. This allows us to create a compactillustration of DB that might be queried by SUs withouthaving to proportion their area with DB, consequently guaranteeing theirlocation privateness. Our suggested schemes provide extraordinary value overall performance characteristics. Our first scheme is based on a simplebut powerful two-party protocol that achieves unconditionalsecurity with a practicable communication overhead with the aid of makingDB send a compacted version of its content material to SU which needshandiest to query this facts structure to analyze spectrum availability.
