Locating the Pollution Sources in Sensornets with a Partial Differential Equation

Xiao-ju Long, Ying-hua Liu and Bin Zhou

Abstract

This study proposed a location model for information sources in sensornets and it can be applied in environment monitoring. A Partial Differential Equation (PDE) is introduced to describe the pollution evolution in a certain region. With the observation data collected by the sensor nodes, several parameters can be determined by an optimization problem. With solving the related partial differential equation, the evolution of the pollution can be represented and the sources can be located easily. It is useful for government and managers to reduce pollution. The efficiency and the accuracy of the proposed model are shown in presented numerical examples.
