In a Cooperative Spectrum Sensing environment, malicious secondary users (SU) degrade the overall performance of the radio network. The existing techniques need to assume an upper bound on the number of such users in a network, to identify them. In the present work, we use the robust distance based on minimum covariance determinant (MCD) to identify the malicious users in the network without assuming such an upper bound. Further, we validate the performance of the proposed RD method in random, always high and always low selfish attacks scenarios.
