An enhanced DV-Hop localization algorithm in Wireless Sensor Networks

Abstract

Localization algorithm is an important and challenging topic in Wireless Sensor Networks (WSNs), especially for the applications requiring the accurate position of the sensed information. An enhanced DV-Hop (Distance Vector-Hop) algorithm is proposed in this paper. The proposed algorithm is derived from DV-Hop algorithm by adding correction to the distance between beacon nodes and unknown nodes to improve localization accuracy. Simulation results show that the enhanced DV-Hop algorithm outperforms the DV-Hop algorithm in localization accuracy without requiring additional hardware and computational cost. © 2014 ISSN 1881-803X.
