基于信任簇的协作压缩频谱感知新算法
New algorithm of trustful cluster-based cooperative compressed spectrum sensing
摘要
Abstract
The spectrum sensing is an important problem to implement the cognitive radio(CR)networks. Some malicious users tamper the data,which will reduce the performance of spectrum sensing. Therefore,the trustful cluster⁃based compressed spectrum sensing(TCCSS)algorithm oriented to the malicious users environment is proposed. The maximum likelihood(ML)is used to estimate the distance between the cluster and primary user,and the distance is compared with the preset threshold to search the trusted cluster. And then the compressed spectrum sensing algorithm is used to detect the channel condition according to the information provided by trustful cluster. The simulation results show that the proposed TCCSS algorithm can deal with the malicious user environment effectively,detect the malicious users accurately,and maintain the high spectrum detection rate.关键词
