Abstract: In this research work, we propose an auction mechanism where Macro Base Station (MBS) - the auctioneer and Small Base Stations (SBS) - the bidders, facilitates the small cells to offload the traffic for the Cellular Network Operator (CNO). In the bidding process the SBSs contest among each other to offload the MUEs, which declares the introductory price. The SBSs decide the price as per supply capacity that includes resources offered by the SBS to offload a number of UEs from MBS to maximise the benefit. The MBS's utility is the difference between the profit earned by saving the power consumption (in terms of energy efficiency) and the total expenditure that MBS has to pay to all the SBSs. If the supply is insufficient, the MBS enhances the effective price so that the SBSs are encouraged to raise their supply amount. The iterative auction progresses till the total supply equals the demand.

Keywords: traffic offloading; small cell; auction mechanism; energy efficiency; cost efficiency; Pareto optimality.
