Energy consumption in mobile phones: a measurement study and implications for network applications

In this paper, we present a measurement study of the energy consumption characteristics of three widespread mobile networking technologies: 3G, GSM, and WiFi. We find that 3G and GSM incur a high tail energy overhead because of lingering in high power states after completing a transfer. Based on these measurements, we develop a model for the energy consumed by network activity for each technology. Using this model, we develop TailEnder, a protocol that reduces energy consumption of common mobile applications. For applications that can tolerate a small delay such as e-mail, TailEnder schedules transfers so as to minimize the cumulative energy consumed while meeting user-specified deadlines. We show that the TailEnder scheduling algorithm is within a factor 2× of the optimal and show that any online algorithm can at best be within a factor
