On Optimality of Myopic Policy in Opportunistic Spectrum Access: The Case of Sensing Multiple Channels and Accessing One Channel

Recent works have developed a simple and robust myopic sensing policy for multi-channel opportunistic communication systems where a secondary user (SU) can access one of N i.i.d. Markov channels. The optimality of the myopic sensing policy maximizing the SU's expected accumulative reward is established under certain conditions on channel parameters. This… CONTINUE READING
