To measure energy consumption across 3G, GSM, and WiFi interfaces and design an optimization protocol that reduces tail energy overhead during mobile network activity.
Measured power consumption profiles and tail energy states across 3G, GSM, and WiFi to build a formal energy consumption model.
Designed and implemented TailEnder, a protocol that schedules delay-tolerant network traffic and aggressively prefetches data to minimize radio wake-ups.
Evaluated protocol performance using real-world user traces across three mobile applications: email, news feeds, and web search.
Demonstrated that TailEnder's transfer scheduling algorithm operates within a factor of 2x of theoretical optimal energy efficiency (compared to a theoretical online limit of 1.62x).
Showed that mobile devices using TailEnder downloaded 60% more news feed updates and retrieved search results for over 50% of web queries while using less overall energy than default policies.
