Recent studies reveal the importance of micro-level pollution information, including human personal exposure and acute exposure to air pollutants. A real-time system with high spatio-temporal resolution is essential because of the limited data availability and non-scalability of conventional air pollution monitoring systems. Currently, researchers focus on the concept of The Next Generation Air Pollution Monitoring System (TNGAPMS) and have achieved significant breakthroughs by utilizing the advance sensing technologies, MicroElectroMechanical Systems (MEMS) and Wireless Sensor Network (WSN). However, there exist potential problems of these newly proposed systems, namely the lack of 3D data acquisition ability and the flexibility of the sensor network. In this paper, we classify the existing works into three categories as Static Sensor Network (SSN), Community Sensor Network (CSN) and Vehicle Sensor Network (VSN) based on the carriers of the sensors. Comprehensive reviews and comparisons among these three types of sensor networks were also performed. Last but not least, we discuss the limitations of the existing works and conclude the objectives that we want to achieve in future systems.<\/jats:p>","DOI":"10.3390\/s151229859","type":"journal-article","created":{"date-parts":[[2015,12,14]],"date-time":"2015-12-14T02:57:29Z","timestamp":1450061849000},"page":"31392-31427","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":318,"title":["A Survey of Wireless Sensor Network Based Air Pollution Monitoring Systems"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8843-0691","authenticated-orcid":false,"given":"Wei","family":"Yi","sequence":"first","affiliation":[{"name":"Department of Computer Science and Engineering, The Chinese University of Hong Kong, Shatin NT, Hong Kong, China"},{"name":"Institute of Future Cities, The Chinese University of Hong Kong, Shatin NT, Hong Kong, China"}]},{"given":"Kin","family":"Lo","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Engineering, The Chinese University of Hong Kong, Shatin NT, Hong Kong, China"}]},{"given":"Terrence","family":"Mak","sequence":"additional","affiliation":[{"name":"Department of Electronics and Computer Science, University of Southampton, University Road, Southampton S017 1BJ, UK"}]},{"given":"Kwong","family":"Leung","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Engineering, The Chinese University of Hong Kong, Shatin NT, Hong Kong, China"},{"name":"Institute of Future Cities, The Chinese University of Hong Kong, Shatin NT, Hong Kong, China"}]},{"given":"Yee","family":"Leung","sequence":"additional","affiliation":[{"name":"Institute of Future Cities, The Chinese University of Hong Kong, Shatin NT, Hong Kong, China"},{"name":"Department of Geography and Resource Management, The Chinese University of Hong Kong, Shatin NT, Hong Kong, China"}]},{"given":"Mei","family":"Meng","sequence":"additional","affiliation":[{"name":"Department of Systems Engineering and Engineering Management, The Chinese University of Hong Kong, Shatin NT, Hong Kong, China"},{"name":"Stanley Ho Big Data Decision Analytics Research Center, The Chinese University of Hong Kong, Shatin NT, Hong Kong, China"}]}],"member":"1968","published-online":{"date-parts":[[2015,12,12]]},"reference":[{"key":"ref_1","unstructured":"World Health Organization 7 Million Premature Deaths Annually Linked to Air Pollution.
