An Improved Node Localization Algorithm Based on DV-HOP in WSN
Efficient sensor node localization algorithm is a research highlight in the applications of wireless sensor networks (WSN). An event information with few node location information is meaningless in practical application. The number and density of nodes shared by unknown-distance node pair are applied to establish close degree model in the paper. The close degree model is also combined with the triangle similarity theory to propose a mathematical model to calculate the distance of single-hop and multi-hop nodes. The simulation results show that the normalized localization error of the improved algorithm is smaller than the conventional DV-HOP algorithm.
