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.
