Energy efficient cross-layer resource allocation scheme based on potential games in LTE-A

In wireless mobile communication system, energy saving is drawing more and more consideration both from the academia and the standardization communities. In this article, a energy efficient cross-layer resource allocation scheme for multi-cell orthogonal frequency division multiplexing (OFDM) network is proposed, and potential game is explored to guarantee the convergence of utility function with pricing. The dynamic cross-layer procedure integrates dynamic resource block (RB) allocation and energy efficiency based power allocation. Simulation results show the proposed scheme find a good balance between quality of service (QoS) satisfaction and energy consumption, and acquires significant improvements in energy efficiency, accompany with good system fairness.
