A cognitive mobile sensor network for environment observation

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.
