Severity Prediction of Drought in A Large Geographical Area Using Distributed Wireless Sensor Networks

In this paper, the severity prediction of drought through the implementation of modern sensor networks is discussed. We describe how to design a drought prediction system using wireless sensor networks. This paper will describe a terrestrial interconnected wireless sensor network paradigm for the prediction of severity of drought over a vast area of 10,000 sq km. The communication architecture for sensor network is outlined and the protocols developed for each layer is explored. The data integration model and sensor data analysis at the central computer is explained. The advantages and limitations are discussed along with the use of wireless standards. They are analyzed for its relevance. Finally a conclusion is presented along with open research issues.
