Localizing primary users using observations collected from secondary users sensing the spectrum is a key aspect for improved operations in cognitive radio networks. However, malicious secondary users may obfuscate their location reports causing disruption in the network operation. In this paper, the authors take a first step towards addressing the challenging problem of primary user localization in the presence of secondary users of varying trust that may randomly obfuscate their reports while maintaining plausibility of their content.
