由于空气污染对公众健康、全球环境和全球经济的重大影响，城市地区的空气质量是现代城市的主要关注点。最近的研究显示了微观污染信息的重要性，包括人体接触和急性接触空气污染物的情况。由于传统空气污染监测系统的数据可用性有限且不可扩展，因此具有高时空分辨率的实时系统至关重要。目前，研究人员集中在下一代空气污染监测系统（TNGAPMS）的概念，并利用先进的传感技术，微机电系统（MEMS）和无线传感器网络（WSN）取得了重大突破。然而，这些新提出的系统存在潜在的问题，即缺乏三维数据采集能力和传感器网络的灵活性。本文根据传感器的载体，将现有的传感器网络分为三类：静态传感器网络（SSN）、社区传感器网络（CSN）和车辆传感器网络（VSN）。对这三种类型的传感器网络进行了全面的回顾和比较。最后，我们讨论了现有工作的局限性，并总结了我们希望在未来系统中实现的目标。
The air quality in urban areas is a major concern in modern cities due to significant impacts of air pollution on public health, global environment, and worldwide economy. 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.
