摘要/Abstract

摘要： 认知无线电网络中,协作频谱感知技术利用多个认知用户的本地感知,克服了多径效应、阴影效应等问题的制约,提高了系统的检测性能。介绍了典型的协作感知系统模型,对本地感知和融合判决这两个关键要素进行了分析,给出了单节点检测与协作感知时的ROC曲线及性能比较。介绍了频谱感知数据篡改攻击、分类以及目前对该攻击的研究现状,针对可能出现的攻击情况,进行了理论分析和仿真,仿真结果表明遭受SSDF攻击后系统性能明显下降。最后总结了全文。

Abstract: In cognitive radio network,cooperative spectrum sensing technology overcomes the problems of multipath effects,shadow effects and such constraints by using local sensing results of cognitive users,hence improves the detection performance．This paper introduces the normal model of cooperative spectrum sensing,analyzes the local spectrum sensing and fusion decision these two key elements,shows the differences of ROC between local spectrum sensing and cooperative sensing．Then presents the concept,classification and state-of-the-art of research of spectrum sensing data falsification attack,we also analyzes and simulates for the possible case,simulation results show that the detection performance decline since be attacked．Finally,we summarize this paper.

Key words: Cognitive radio,Cooperative spectrum sensing,SSDF attack,Detection performance
