Pareto optimal primary–secondary user dynamic spectrum leasing game
Seyyed Mohammadreza Azimi · Electronics Letters · 2014
Dynamic spectrum leasing provides a room for better spectrum utilisation. Primary user (PU) temporary leases its unused spectrum in exchange for monetary profits and secondary users (SUs) opportunistically use the available spectrum. Recent works proposed a non‐cooperative game to model PU–SU interaction, but the outcome is not Pareto efficient. The SUs’ utility is modified to indicate their opportunistic behaviour. In addition, the outcome of the non‐cooperative game would be Pareto efficient. Simulation results verify that the proposed method outperforms the conventional one.
