Data Clustering on a Network of Mobile Smartphones

We present Dowser, a system for data clustering in a network of mobile smart phones. Dowser comprises three components: (a) a distributed framework, implemented on mobile phones that eases the programmability and deployment of applications on the devices using simple programming primitives, (b) a data gathering component that tracks the movement of wireless device owners and collects wireless connectivity data, and (c) a clustering algorithm that allows users to combine their individual data, that is distributed and energy efficient. Our detailed experimental results over our test bed of Nokia N95 8GB smart phones, illustrate that our system is practical, depicts good performance and has low energy and resource overhead.
