摘 要：Node localization is one of the key technologies in wireless sensor network.This paper proposed an improved RBDMCL algorithm based on traditional MCL algorithm,which can reduce the sampling areas and improve the positioning accuracy by building a node motion model.Then concludes by simulation analysis and comparison that RBDMCL has higher positioning accuracy than MCL in the anchor node density and node velocity.
