GPS-Free Accurate Energy-Efficient Outdoor Localization






Dejavu Basic Idea CellSense

Location-based services (LBS) have become an integral part of our daily life with applications including car navigation, location-based social networks, and context-aware predication and advertisement. Different LBS require different localization accuracies; Generally, GPS is considered the de facto standard for ubiquitous and accurate outdoor navigation. However, GPS is an energy-hungry technology that can drain the scarce battery resource of mobile devices quickly. In addition, its accuracy is limited in areas with obscured access to the satellites, e.g. in tunnels and many urban areas.
To address the GPS deficiencies, a number of outdoor localization systems have been proposed over the years. However, this saving in energy usually comes at a reduced localization accuracy.

In this project, we aim to develop ubiquitous GPS alternative systems that is capable of achieving both energy efficiency and high localization accuracy. In particular, the project targets the development of accurate outdoor localization systems for mobile devices by utilizing the different sensors available on the phone.
