Using Mobile Pixel To Evalutae Wireless Sensor Network’s Ployment

Through wireless sensor network (WSN) nodes which installed on the mobile equipment suchas motor vehicle or cellular mobile telephone and sensor data different time get from nodes, wecan build dynamic WSN network model.Now the wireless sensor network have important applications in the field ofmilitary,transportation,environmental monitoring and so on. But because the wide areadistribution and expensive instrument make the construction of wireless sensor networkexpensive,so the key is having an good deployment plan.This paper introduce a concept of mobile pixel to evaluate the quality of WSN deploying,theWSN data are interpolated with Delaunay triangularization interpolation method and the Naturalinterpolation method, comparising and calculating two kinds of interpolation, getting the datamatrix similarity and then get the mobile pixel.Final do the experiment in hill bihand the ZheJiangagriculture and Forestry University with wireless sensor nodes, and collecting data,deleting thesingular point, standardizing, then calculate the mobile pixel combined with MATLABprogramming.The experiment results show that the mobile pixel can accurately calculate the approximationof true value in few hundred nodes,which can reasonable comparise different prior data,and canprovide basis and good plan for the late research.
