Optimal Channel Exploration for Cognitive Radio Networks
Linbo Zhai, Feng Juan Yang · Advances in computer science research · 2015
In this paper, the optimal channel exploration is proposed for cognitive radio networks.In the networks, primary users (PUs) utilize the channels with fixed slot structure.Cognitive users (CUs) should sense the channels within each slot.We study the relationship of the channel states between the nearby slots and range channels by the decreasing idle probabilities of all channels.Then we use stop rule to address the channel exploration problem, which makes CUs to access the optimal idle channel.The simulation results show our proposed scheme can obtain higher throughput.
