Selection of Nodes and Sensors for Monitoring of Air Pollutants Related to City Traffic

Abstract

Air pollution is a serious problem all around the world. One of the largest producers of air pollutants is city traffic. Several pollutants are usually monitored and analysed in stationary stations. Nowadays the ICT development alllows to observe them by various technologies, mainly by wireless sensor networks. Wireless nodes equipped by sensors are small sophisticated devices which can be distributed either in internal or external environment and which can obtain data about selected variables. The selection of wireless nodes and sensors is a crucial decision process which has to be considered at the beginning of wireless sensor network design. This paper introduces a set of criteria for selection of nodes and sensors of wireless sensor networks for monitoring of air pollutants related to city traffic. The selection process is based on defining of eight groups of criteria with determined weight values. The optimal parametres of criteria for wireless sensor network are defined and argued. The final selection analysis determines the most suitable option for air pollutants monitoring related to city traffic from the offered options. © Springer International Publishing Switzerland 2014.
