A new Dv-hop algorithm in wireless sensor network

This article mainly talks about the self-localization technology arithmetic of WSN. Through farther analysis and simulation, aiming at the two problems of Dv-hop, this article brings forward an improved arithmetic in which a leveled flooding method and a hop-weighted localization calculation method is adopted. In the new arithmetic not only the communication coat of the network is reduced greatly, but also the far anchor´s effect is reduced much more. This choosing policy is more reasonable, especially in anisotropic networks.
