To offload or not to offload? The bandwidth and energy costs of mobile cloud computing
TL;DR: This work studies the fmobile software/data backupseasibility of both mobile computation offloading and mobile software/ data backups in real-life scenarios and gives a precise evaluation of the feasibility and costs of both off-clones and back-Clones in terms of bandwidth and energy consumption on the real device.
Proceedings ArticleDOI
Signals from the crowd: uncovering social relationships through smartphone probes
TL;DR: A simple and automatic methodology to build the underlying social graph of the smartphone users, starting from their probes, and shows that, by looking at the probes in an event, one can learn important sociological aspects of its participants---language, vendor adoption, and so on.
