2013 Proceedings of the 11th ACM Conference on Embedded Networked Sensor Systems - SenSys '13  
PCS uses this model to drive a decision engine that lets the smartphone locally decide which app opportunities to exploit based on expected energy/quality trade-offs.  ...  For instance, the energy burden of sampling certain sensors (such as WiFi or GPS) can quickly accumulate to levels users are unwilling to bear.  ...  For example, an opportunity to sense based on a particular app running on the foreground is evaluated with utility depending on an expected level of sample quality (app category specific, see §4.3 for  ...
