Progressive partition and hop-weighted positioning algorithm in wireless sensor network
Cheng Yi · 2013
To improve Distance Vector-hop(DV-hop),a progressive partition and hop-weighted calculation method is introduced.Through classifying the anchor nodes into several levels,then flooding beacons limited in their local area separately,the communication amount of the network is reduced greatly.The anchor nodes are given different weights according to their hops during the adjusted value calculating and propagating.Through the theoretical calculation and simulation,the communication cost of the positioning is cut greatly,and the positioning accuracy is improved.Especially in anisotropic topology,its positioning accuracy is much higher than that of DV-hop.
