Defense strategies have been well studied to combat Byzantine attacks that aim disrupt cooperative spectrum sensing by sending falsified versions of data a fusion center. However, existing studies usually assume network or attackers as passive entities, e.g., assuming the prior knowledge is known fixed. In practice, can actively adopt arbitrary behaviors and avoid pre-assumed patterns assumptio...
