Abstract
Wireless sensor networks have been used for
environmental monitoring over the last twenty years. This paper presents an
architecture based on a Wireless Mesh network of sensors (WMNS) to measure air
pollution in areas where there is a lack of internet access. We are motivated
by the fact that air pollution is emerging as a key threat to health,
environment, economy and the quality of life for millions of people; as
urbanisation, motorization and economic activity increases. The situation
becomes critical when the concentration of air pollution is high. So there is a
necessity to develop an indicator concerning air pollution. The only solution to
this problem is based on the recent research in Wireless Mesh Networks for
internet connectivity in urban and rural areas. This system was successfully
developed and implemented in a short time, with low budget and limited human
resources in European countries. The information from these sensors gives the
air quality status of some harmful gases like NO2, NO, O3, CO,
CO2. The information also helps to manage the urban air quality by
controlling factors such as road traffic.
