In this letter, we propose a novel dynamic cell on/off scheduling algorithm in small cell networks based on the Stackelberg game. The objective of the proposed algorithm is to optimize the packet throughput performance with a tradeoff of energy consumption. In our system-level simulations, the proposed algorithm exhibits considerable performance gains, in terms of packet throughput per unit of energy consumption, compared with two existing algorithms respectively based on random on/off and packet arrival-triggered cell activation.

Green communication receives a growing number of concerns due to the consideration for energy and environment issues. On the other hand, the evolution of mobile and wireless communication also results in heterogeneous Radio Access Technologies (RATs), such as Wi-Fi, UMTS, LTE, CDMA2000 and so on. As a result, energy saving by inter-RAT cooperation has raised significant discussions in both industrial and academical worlds. In this paper, we concentrate on inter-RAT energy saving for multicast services. Moreover, we use Integer Linear Programming to model the problem and propose a distributed algorithm which can efficiently save the energy consumption. [ABSTRACT FROM PUBLISHER]
