Cognitive radio networks (CRNs) Become a promising answer for overcoming the lack along with ineffective make use of bandwidth sources by means of permitting secondary user (SUs) to get right of entry to the primary users' (PUs) channels so long as they do now not intervene with them. Despite its significance, the location privateness trouble in CRN s simplest recently won interest from the research network. Some works centered on addressing this difficulty in the context of collaborative spectrum sensing while others targeted on addressing it inside the context of dynamic spectrum auction. However, those works did no longer focused on the place privacy of the customers. within term paper, we suggest location privateness-preserving schemes for database-pushed CRNs. The first scheme, location privateness in database-driven CRNs (LPDB), provides finest place privateness to SUs within DB’s coverage place by means of leveraging set club statistics structures (used to test whether or not an detail is a member of a hard and fast) to construct a compact version of DB. The second scheme, LPDB with servers (LPDBQS), minimizes the overhead at SU’s side at the fee of deploying an extra the network.
