Online visualization of Urban Noise in Ubiquitous-city Middleware

In this paper, we propose the online visualization of Urban Noise as a part of Smart Ubiquitous Middleware (SmartUM). Since the middleware includes the visualization function, the applications in the u-city portal which want to use noise maps, don't need to include the processing mechanism to make noise map. This paper explains how the online visualization is done in cooperation with other functions of the middleware.
