Energy-Efficient Clustering WSN System for Environment Monitoring Applications

Air pollution is considered critical to people's comfort, health and safety. In both environments (indoor and outdoor) air pollution can be controlled using a small amount of inexpensive sensing units distributed across an area of interest for measuring the levels of different critical gasses such as CO, H2S and NO2. The monitoring process is critical. The deployment of the Wireless Sensor Network offers an alternative solution by scattering a large number of disposable sensor nodes across an area of interest. Scientists may directly retrieve sensed data via a web server application from the sensor area. This paper offers an extensive review of the approaches available to support the environmental monitoring of the wireless sensor network.
