Abstract

The life of battery power available time is a crucial character of the battery powered mobile device. In this paper, we investigate the performance issues of upper layer protocol, such as TCP, in IEEE 802.11 LAN´s power saving mode. We discuss the tradeoff of energy saving, networking throughput and response time at the points of user experience. A novel power efficiency scheme is proposed to control the traffic transmission in power saving mode, which takes the QoS requirements of applications into account. Finally, we show that the proposed schema achieves higher user experience in our experiment.
