An Improved DV-Hop Localization Algorithm Based on Hop Distance and Hops Correction
In order to solve the problem that the DV-Hop algorithm has large error in the network topology environment of random distribution of nodes, this paper proposes a WSN localization algorithm based on hop distance correction. The algorithm uses the method of multi communication radius to correct the hop number within 1 hops, which makes it more consistent with the real situation; Then, the weight...
متن کاملLSDV-Hop: Least Squares Based DV-Hop Localization Algorithm for Wireless Sensor Networks
—Wireless Sensor Networks (WSNs) have increasingly become a hot spot of research and application in the fields of computer networks and telecommunications. It is undoubtedly one of the most important issues for WSNs to search an accurate and effective localization method. In this paper, an improved DV-Hop localization algorithm, called least squares DV-Hop (LSDV-Hop), is proposed based on the ...
متن کاملAn Improved DV-Hop Wireless Sensor Network Localization Algorithm
The positioning accuracy is not high for the range-free localization algorithm DV-Hop in wireless sensor networks and the Particle Swarm Optimization algorithm is proposed to optimize the positioning accuracy of the DV-Hop and the IDV-Hop localization algorithm is also proposed. Firstly, the IDV-Hop utilizes DV-Hop to estimate the measuring distances between nodes to be positioned and the beaco...

متن کاملAn Improved Dv-Hop Localization Algorithm Based On Machine Learning For Wireless Sensor Network
The DV-Hoplocalization method has a series of superiorities, such as high distributiveness and expandability, which is perfectly fit for large-scale deployment. Moreover, it may lead to reasonable positioning accuracy merely in isotropous dense network. In practical environment, most scenes are anisotropic, with unevenly distributed nodes. In this paper, kernel PCR method is applied to collect ...
