MAUI: making smartphones last longer with code offload
TLDR
MAUI supports fine-grained code offload to maximize energy savings with minimal burden on the programmer, and decides at run-time which methods should be remotely executed, driven by an optimization engine that achieves the best energy savings possible under the mobile device's current connectivity constrains.

DTN routing as a resource allocation problem
TLDR
RAPID is presented, an intentional DTN routing protocol that can optimize a specific routing metric such as worst-case delivery latency or the fraction of packets that are delivered within a deadline and significantly outperforms existing routing protocols for several metrics. Expand
Energy consumption in mobile phones: a measurement study and implications for network applications
TLDR
TailEnder is developed, a protocol that reduces energy consumption of common mobile applications and aggressively prefetches several times more data and improves user-specified response times while consuming less energy. Expand
Augmenting mobile 3G using WiFi
TLDR
A system, called Wiffler, to augments mobile 3G capacity in mobile environments and significantly reduces 3G usage, using two key ideas leveraging delay tolerance and fast switching -- to overcome the poor availability and performance of WiFi. Expand
How Speedy is SPDY?
TLDR
A systematic study of Web page load time (PLT) under SPDY and compare it to HTTP finds that SPDY provides a significant improvement over HTTP when the authors ignore dependencies in the page load process and the effects of browser computation. Expand
Demystifying Page Load Performance with WProf
TLDR
This work presents WProf, a lightweight in-browser profiler that produces a detailed dependency graph of the activities that make up a page load, and finds that computation is a significant factor that makes up as much as 35% of the critical path, and that synchronous JavaScript plays a significant role in page load time by blocking HTML parsing. Expand
Interactive wifi connectivity for moving vehicles
TLDR
ViFi is developed, a protocol that opportunistically exploits basestation diversity to minimize disruptions and support interactive applications for mobile clients that doubles the number of successful short TCP transfers and doubles the length of disruption-free VoIP sessions compared to an existing WiFi-style handoff protocol. Expand
An In-depth Study of Mobile Browser Performance
TLDR
An in-depth pairwise comparison of loading a page on a mobile versus a non-mobile browser is performed, and the composition of the critical path during page load is different when loading pages on the mobile versus the non- mobile browser. Expand
DTN routing as a resource allocation problem
TLDR
RAPID is presented, an intentional DTN routing protocol that can optimize a specific routing metric such as worst-case delivery latency or the fraction of packets that are delivered within a deadline and significantly outperforms existing routing protocols for several metrics. Expand
