An Improved DV-HOP on Weighted and Distributed Calculation Method

Abstract:

In DV-HOP algorithm, the average one-hop distance is calculated by using the centralized calculation and broken line replacing straight line method. Thismethod causeslocalization errors.In view of the localization errors,we propose an improved DV-HOP on weighted and distributed calculation method (WD-DVHOP) in this paper. In the WD-DVHOP, we replace the centralized and distributed calculation method by a weighted calculation method.The distance between unknown nodes and anchor nodes is calculated by a method, which the average one-hop distance of each anchor node multiplies by hops count between unknown nodes and anchor node.Simulation result shows that average localization error is reduced in the WD-DVHOP, in case of less anchor nodes and smaller communication radius.
