Abstract: As participants of intelligent networks, secondary users should first act as sensors to detect wireless environment to get available spectrum. However, to get more accurate sensing data and access idle spectrum with higher probability in cognitive radio networks, secondary users have to share positions with other entities such as fusion centers, which may raise serious privacy concerns if these positions are not protected adequately. In this paper, to make full use of idle spectrum with low probability of location leakage, we propose a Location Privacy-Preserving Channel Allocation (LP-p CA) scheme. The scheme can conceal identities of secondary users and cut off the relationship between secondary users' location and register data in database (DB) while using random sequence and self-coexistence mechanism of agents. Simulations show that the proposed scheme can satisfy users' personal location privacy concerns and maximize spectrum utility synchronously.
