A Distributed Health Navigation System based on opportunistic mobile WSN

Accurate pollution monitoring in urban environment requires an extremely large number of measurement station. The very complex 3D structure of urban area and its fluid dynamic behavior cause to be necessary very dense sampling grid to evaluate quantitative pollution indexes that can be correlated to real observed health effects or to obtain accurate pollution trend analysis. In order to reduce the high building cost and the management complexity of these high density monitoring grids, some papers proposed mobile monitoring stations to piggyback on public buses obtaining more dense sampling grid with fewer stations. In this paper we propose an Health Navigation System application for smartphone, based on a network of low cost, high precision, miniaturized wireless mobile monitoring system that can be easily embedded on bike frame. The mobile network makes available an accurate pollution urban map to our Navigation System that bikers can use to determine the healthiest route.
