Demo abstract: Efficient data retrieval for interactive browsing of large sensor network data sets

Data gathered from sensor networks can easily reach the dimension of millions of data points. While there exists a great variety of sophisticated components for web-based data visualization, efficient and timely data retrieval is a non-trivial problem when dealing with large data sets. In this paper, we present a client-server architecture for a web application that allows a user to interactively browse through thousands or even millions of data points without having to sacrifice detail.
