“…To solve these problems, many researchers have proposed many schemes to improve location accuracy of DV-Hop algorithm [14][15][16][17][18]. In [14], the authors proposed a new localization algorithm and improve the DV-Hop algorithm by using a differential error correction scheme that is designed to reduce the location error accumulated over multiple hops.…”

“…In [16], Boukerche et al, proposed a novel localization-based protocol and show how Voronoi diagrams can be used efficiently to scale a DV-Hop algorithm while maintaining and reducing further DV-Hop's localization error. In [17], Zhang et al, used correction value as the estimated distance between anchor nodes and unknown nodes and Total Least Squares(TLS) to enhance the localization accuracy. In [18], Gao et al, formulated the hopdistance relationship for quasi-UDG model in WSNs where sensor nodes are randomly and independently deployed in a circular region based on a Poisson point process.…”

Abstract.For the disadvantage which is larger positioning error, the RSSI signal strength is used to calculate the hops between the sensors which make it more close to the real network; Meanwhile, the hyperbolic method is adopted to improve the unknown node location which eliminates the cumulative error and improves the positioning accuracy. Simulation experiments show that the positioning error of improved algorithm is better than DV -Hop algorithm that reduced by 15% or so, and the best case, the positioning error decreases to 15%, meets the demand of sensor network localization accuracy.

An improved DV-HOP localization algorithm is proposed based on the traditional DV-HOP localization algorithm in the paper. There will be a big error that using the nearest anchor node's average hop distance instead of the average hop distance of all the anchor nodes that involved in the localizing in the traditional DV-HOP localization algorithm. Therefore, the improved algorithm introduces threshold M, it uses the weighted average hop distances of anchor nodes within M hops to calculate the average hop distance of unknown nodes. In addition, the positioning results are corrected in the improved algorithm. The simulation results show that the new localization algorithm effectively improves the positioning accuracy compared with the traditional DV-HOP localization algorithm, it is an effective localization algorithm in the wireless sensor networks.
