Abstract

Cognitive radio technology enables secondary users to access to licensed spectrum under the premise of not interfere with the primary user in the network, but it also brings a lot of new hidden security. To grasp timely and accurately the attack situation over a wide range when malicious users emulate the primary user to attack the channel, and to display correctly spectrum situation, this paper proposes a PUEA detection-based situation awareness scheme for research the interference situation of malicious users. Decision-makers can know well the attack situation over a wide range, by detecting the PUE attacker's energy and location and building the interference situation, and drew the interference into a situation map. This method can separate the energy and position of the primary users and malicious users, so as to fully exploit the potential of spectrum holes to improve the accuracy of the spectrum map, and improve safety and system capacity of the channels.
