Title Decentralized Cognitive MAC for Opportunistic Spectrum Access in Ad Hoc Networks: A POMDP Framework.
Publication Date Apr 2007
Media Count 14p
Personal Author A. Swami L. Tong Q. Zhao Y. Chen
Abstract We propose decentralized cognitive MAC protocols that allow secondary users to independently search for spectrum opportunities without a central coordinator or a dedicated communication channel. Recognizing hardware and energy constraints, we assume that ...
