Offline Trace Synchronization for Smartphone Energy Profiling

Energy profiling is a means to effectively understand the power behavior of smartphone applications. However, no tool that effectively combines portability, accuracy and automation has been proposed yet. In this thesis a new approach is proposed, which sets the basis for such a tool by solving a trace synchronization problem. TRAce Merger uses...

Indoor Localization using Accidental Infrastructure

We can foresee a near-future scenario where a huge number of semi-intelligent devices are part of our everyday environment, our homes, the public places and the office as well. The intelligent thermostat uploads the temperature readings to an online database; the fridge sends a tweet when we are out of milk; the coffee machine texts us when the...

Interactive Design Studio: A spatial-computing framework fro non-IT specialists

In recent years, application domains outside information technology such as architecture have shown an increasing interest in the capabilities of networked systems such as localized computation, reduced power-consumption, and distributed interaction. These capabilities incline the design of interactive environments towards the IT-domain. In...

Offloading mobile data traffic to Wi-Fi through MASS-ANET: Mobile assisted ad-hoc networking

Massive sales of smartphones and tablets have enabled more people to access the internet with a 3G connection than ever before. Predictions indicate an exponential growth of mobile data traffic world-wide reaching 6.3 exabytes per month by 2015, a 26-fold increase over 2010.
