A New Approximation to Information Fields in Sensor Nets

Wei Wei, Bin Zhou, Ang Gao and Yiduo Mei

A number of practical events result in a natural information potential field in the proximity of the phenomenon. A novel method is proposed in this study to approximate the information potentials fields in Wireless Sensor Networks (WSNs). The moving least-square method is introduced to solve related Partial Differential Equations (PDEs). This equation determines a smooth edition of the intrinsic potential field maintained major characters which is propitious to most applications of WSNs. For instance, navigation in parking yards, temperature, motion or pollutants, etc. The association between the nodes and the local information level are also considered in this method. Various information potentials fields can be integrated together naturally attribute to the well property of the PDEs. Efficiency and stability of our scheme are verified by numerical examples. The simulation results make clear that the presented way is advantageous to be used in WSNs.
