In database-driven cognitive radio networks, location inference attack may cause location privacy leakage of secondary users. Malicious entities could geo-locate secondary users with spectrum utilization information. The efficiency of existing solution largely depends on the stability of available spectrum. Most solutions are not effective because of the unpredictable return of primary users. To prevent location inference attack, we propose an Agent-based Channel Selection(ACS) scheme in this

In this scheme, the database allocates spectrum with self-coexistence mechanism to avoid interference, and each base station registers spectrum information as an agent in the database instead of secondary users (SUs). Thus, the proposed scheme can decrease the probability of being geo-located for SUs effectively. According to the simulation, we analyze the relationship among the factors that impact the probability and the efficiency of the proposed scheme.
