ABSTRACT
Air pollution is a serious problem all around the world. The highest contribution to
rising emissions in the air is caused by burning of fossil fuels and transportation. Road traffic is a big problem in cities and developing countries where the number of cars is increasing. The major pollutants which are related to transportation are NOx, COx and VOC. It is necessary to monitor the values of these pollutants because they have to be held below their highest allowed limits. Wireless sensor network seems to be a good technology for measuring values of air pollutants in cities. Every wireless sensor network consists of (wireless) nodes equipped with needed sensors, gateway and server. The biggest advantage of this technology is that data are collected in a real time so that the most endangered areas can be warned in time. Nodes can be distributed in the area of interest with high density so that detailed information about air pollutants is obtained. Data obtained by sensors, recorded in nodes are sent to a gateway and resent to a server for a long time storage. This study focuses on usage of wireless sensor networks for monitoring of air pollutants related to traffic. Criteria for the selection of nodes with integrated demands on needed sensors were determined and evaluated by their importance. The optimal parameters for
application of this kind of wireless sensor network were specified. Weight values of the selected criteria were established on the basis of four methods. The computed values of weight for determined criteria were compared and visualized. The most appropriate method for this kind of task was chosen. Determination of criteria and their weight values is a basis for selection of the most suitable nodes, sensors for determined task.
