Q-Learning Based Bidding Algorithm for Spectrum Auction in Cognitive Radio Zhe Chen, and Robert C. Qiu, Tennessee Technological University Introduction

Numerical Results

Spectrum auction can be employed to allocate detected available frequency bands to secondary users (SUs). In this paper, a bidding algorithm based on Q-learning for SUs is proposed. SUs employ the proposed algorithm to learn from their competitors and automatically place better bids for available frequency bands. Simulation result shows the proposed algorithm is effective.

Q-Learning Algorithm

Number of available frequency bands and SUs’ credits

Proposed Bidding Algorithm

SUs’ total bids and maximum bids

SUs’ buffer fullnesses and total sent data

Conclusion • A bidding algorithm based on Q-learning has been proposed. • Simulation results show the proposed algorithm is effective. Acknowledgments to National Science Foundation and Office of Naval Research
