抗伪装SSDF恶意攻击的合作频谱感知方法
Cooperative spectrum sensing method considering anti camouflage SSDF malicious attacks
摘要
Abstract
We propose a segmented trust value update and defense scheme after considering a more practical cognitive radio network , where malicious users are able to camouflage themselves . First , we choose slow growth and fast recovery of the trust value update mechanism ,determine which energy interval the reporting energy value of the node belongs to , and then reduce the malicious node trust value by dynamically updating the trust value and urge the poor performance node to improve its sensing efficiency . Simulation analysis using the Monte Carlo method is made to show the effectiveness of opposing malicious attacks , and guarantee the network performance and throughput .关键词
