提出了多天线下基于能量特征的MAC协议识别方法。方法以TDMA和Slotted Aloha分别作为基于控制和竞争MAC协议的代表,在多天线环境下,基于接收能量均值和能量方差作为特征,利用支持向量机技术对分别来自两个MAC协议未知的主网络的特征样本进行识别。理论分析和仿真结果表明,多天线环境下的MAC协议识别准确率要比现有的单天线算法有更好的性能。
提齣瞭多天線下基于能量特徵的MAC協議識彆方法。方法以TDMA和Slotted Aloha分彆作為基于控製和競爭MAC協議的代錶,在多天線環境下,基于接收能量均值和能量方差作為特徵,利用支持嚮量機技術對分彆來自兩箇MAC協議未知的主網絡的特徵樣本進行識彆。理論分析和倣真結果錶明,多天線環境下的MAC協議識彆準確率要比現有的單天線算法有更好的性能。

This paper presents a novel MAC protocol identification method based on energy features of the multi-antenna.To classify contention based and control based MAC protocol in an unknown primary network, we choose the received power mean and variance as two features for support vector machines in multi-antenna environment.Theoretical analysis and simulation results show that MAC protocol recognition accuracy of multi-antenna environment is better than that of the present single-antenna environment.
