Low power embedded controlled sensor network for agricultural applications

Designing low power embedded controlled sensor networks is always the interest of engineers, scientist and the users. It is desired to have a sensor network which requires little power thereby saving cost and the inconveniences of having to replace batteries in some difficult access areas of usage. In this paper novel approaches to implementation of an energy efficient embedded sensor network are analyzed and benchmarked. The main focus is on exploring energy efficient mechanisms to minimize the energy at various block levels such as the micro-controller, the communicating radio, and the sensors. The issue is also to investigate a low power mechanism by proposing an application specific micro-controller and energy efficient clustering algorithm. The paper also describes the implementation of sensor applications for agriculture, such as measurement of soil humidity, luminosity and temperature etc. The proposed agricultural embedded controlled system collects the soil information through sensors and sends it by a linux based router to the internet.
