An Improved DV-HOP Localization Algorithm in Wireless Sensor Network
Journal Title: 河南科技大学学报(自然科学版) - Year 2016, Vol 37, Issue 6
Abstract
For the poor performance of distance vector-hop( DV-Hop) location algorithm in positioning accuracy caused by irregularity and mirror error in the large scale of wireless sensor networks,an improved DVHOP localization algorithm was proposed. The error correction method for the irregular wireless sensor networks based on node degree was proposed. Due to the large scale of nodes deployed in area,the node error brought by mirror error was inevitably,so a new error correction method for location error based on semi-circle model was proposed. Simulation results show that the improved algorithm obtains 6% of position accuracy improvement better than those existing improved algorithms. It can weaken the mirror error effectively,so it can better achieve real-time precision localization for unknown nodes.
