Air Pollutant Source Location based on Zigbee Wireless Network and Optimized Least Square

摘要

This paper proposed an air pollutant source location system with the combination of the wireless sensor network (WSN) technology based on Zigbee wireless network and an optimized least square method. The system, which can realize the coarse location of the possible air pollutant sources, is illustrated in detail from the factors of technology, architecture and working scheme. This paper also proposed an optimized monitoring method applied to each Zigbee node named cycle pollutant monitoring to reduce the amount of transmission data. The paper finally concluded the advantages as well as the disadvantages of the current system, and made a brief statement of two possible optimization directions.
