Abstract
In this thesis, we have designed a mobile application that can simplify the management, data collection, and communication among team members during field studies. The application handles both real-time and offline field study management. It allows scientists to: (1) design a field outing, (2) share logistical plan with all participants in real-time, (3) share the geographic location and actions performed by all users, (4) enable real-time communication exchange, (5) log the trip events and collect statistics for future data analysis. However, a key challenge is to ensure that the mobile devices would have enough power to carry out the experiment. To this end, we first worked with educators to define all functionalities and fit them into different stages of a field study. We then profile the energy consumption of our application on real mobile devices and propose a power model that estimates the power usage of the application according to user actions. Based on this model, we develop a power controller module, which dynamically adjusts power usage of the application. It maximizes the user experience but saves enough battery life to meet the desired duration of the field study. We show that our model can predict the energy consumption in different scenarios with an error less than 2% compared to real power measurements.
