Application-Centric Wi-Fi Energy Management on Smart Phone

Vast majority of the services running on the smart phone today are networked in that significant amount of communication is required. Smart phone energy expenditure due to Wi-Fi communications constitutes significant portion of the battery discharge. In this paper, the authors first investigate the key factors influencing Wi-Fi energy consumption, and propose three energy management schemes: dynamic control of Wi-Fi on/off interface; improve communication efficiency via application packing; and elongation of Wi-Fi Power Save Mode (PSM) via application alignment under mixed application workload.
