Energy-efficient scheduling for cloud mobile gaming

In this paper, we study the problem of wireless schedulers for cloud-based wireless gaming systems, with focus on energy efficiency issues. While green communications and networks have been widely studied in recent years, the rise of gaming based on wireless clouds introduces many specific aspects allowing important savings and improvements. We try to minimize the power consumption of this type of networks in a hybrid WiFi/LTE radio access network (RAN) by proposing a novel Wireless Cloud Scheduler (WCS) mechanism and applying different utility functions. We find that it is possible to reduce the power consumption, increase the maximum attainable capacity of the network in terms of number of served UEs and minimize the costs of cloud resources usage, while maintaining a good level of QoS.
