Abstract :
With the development and extensive application of Wireless Sensor Networks(WSN) technology, Wise medical Treatment has entered the ordinary household. A patient positioning System is designed based on WSN in this paper. Distance Vector-Hop (DV-Hop) algorithm is used by through analyzing the system working environment, and some improvement has made on the basis of it´s error analysis. There are two improved aspects. The anchor nodes are filtered. A certain weight value is added in coordinate calculation. Finally, the influence factors of positioning accuracy are studied by the simulation.
