Nowadays, with the development of industrialization and urbanization, air pollution has been a serious problem all of the word. Air pollutant is harmful to human and ecological environment, for example, SO2 and NO2 produced by industry are vital to living organisms, greenhouse air such as CO2 causes global warming. As a result, environmental monitoring is of great importance for human beings.This paper proposes a scheme to implement environmental monitoring. In particular, wireless sensor network collect data from surrounding environment and mobile communication system receive and process these data. To avoid network congestion, a cognitive protocol is proposed for wireless sensors accessing to mobile network. Besides that, a dynamic working scheme is also proposed for sensors so that data collection rate can be adapted to the situation of network.
