creator Zhou, Chenyang advisor Cheng, Yu As wireless applications are increasingly prevalent in recent years, smartphones, the link between wireless world and common life, become more and more indispensable. Subsequently, smartphone applets become more and more complicated, protocols like 3G,LTE,4G have also been improved to satisfy people’s increasing requirement. This leads to an exponentially increase in energy consumption. However, the power of smartphone battery is limited, and thus how to improve energy efficiency and extend the life-time of smartphone battery becomes a critical issue. In wireless local area networks (WLANs), switching to low-power sleep mode to save energy is common. Power-Saving mode (PSM) was one of the standard algorithm in order to save energy. This feature allows devices to switch the WiFi on and off several times a second. However, research papers have shown that PSM is not really efficient in practice, and in many cases (e.g. multiple stations), can actually degrade performance. This sleep-scheduling algorithm, derived from GreenCall Algorithm is demonstrated to have lower packets loss rate while achieving higher energy efficiency than that of the existing GreenCall Algorithm.
