Abstract: Sensornets is an important activity in the fields of computer science. Every sensor node collects the information and cooperates with others for certain purpose. A smooth version of the information distribution on the nodes is expected for some applications. Partial Differential Equations (PDEs) are introduced to determine such information potential fields and they can be solved by some numerical methods. The solutions preserve major features of original distributions which are advantageous to most applications such as navigation in parking lots, environment monitoring, etc. The simulation results show that such methods are convenient to be applied in sensornets.
