A novel optimized model of distributed multi-hop Cognitive Medium Access Control( C-MAC) protocol with a single transceiver was proposed to handle two restrictions in MAC protocol of Mobile Ad Hoc NETwork( MANET).One is the restriction of multiple transceivers and payload imbalance in different channels,and the other one is the restriction of multi-hop and control overhead.Firstly,channel sensing and data transmission of the new C-MAC protocol were realized in ATIM(Announcement Traffic Indication Message) w...

0引言认知媒体接入控制协议(Cognitive Media Access Control,C-MAC)是IEEE工作组针对静态频谱分配算法中的频谱“白洞”问题[1],于2005年提出的新型协议模型,以高吞吐量和信道利用率等优势,受到国内外学者的广泛关注,且协议正由中心控制网络向Ad Hoc类网络演进[2]。移动自组网
