Wireless sensor networks can be widely applied in many fields.The primary problem to be solved is node positioning.A new range-free positioning algorithm was proposed,based on particle dynamics of physics.Besides the common advantages of all range-free positioning algorithms,the new algorithm can reduce the average positioning error to 16% of nodal communication distances.The approaches used,and simulation results with the new algorithm were discussed.The new algorithm was compared with the distance vector_hop(DV_Hop) algorithm,and the average positioning error of the new algorithm is almost half that of the DV_Hop algorithm,and the neighbor relationship satisfaction rate of the new algorithm is 100% while the DV_Hop algorithm's rate is less than 90%.On the other hand,the new algorithm does need much more positioning time.
