A Selective 3-Anchor DV-Hop Algorithm Based On the Nearest Anchor for Wireless Sensor Network
Abstract—Information of nodes’ locations is an important criterion for lots of applications in Wireless Sensor Networks. In the hop-based range-free localization methods, anchors transmit the localization messages counting a hop count value to the whole network. Each node receives this message and calculates its own distance with anchor in hops and then approximates its own position. However th...
متن کاملStudy on DV-Hop Algorithm Based on Modifying Hop Count for Wireless Sensor Networks
Localization is an indispensable part in wireless sensor networks. In consideration of its importance, extensive research has been carried out resent years. On account of the process that DV-Hop algorithm is implemented in anisotropic density sensor networks, there can be a big localization error in local area, where the information transfer has excess hop counts between two nodes. We proposed ...
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 with Reduced Node Location Error for Wireless Sensor Networks
In this paper, we propose 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. This scheme needs no additional hardware support and can be implemented in a distributed way. The proposed method can improve location accuracy without increasing communication traffi...
متن کاملAdaptive DV-HOP Location Algorithm Using Anchor-Density-based Clustering for Wireless Sensor Networks
Localization is an important topic in the wireless sensor networks (WSN) because sensor nodes are randomly scattered over a region and can get connected into a network on their own. In this paper, we proposed an adaptive DV-HOP location algorithm using anchor-density-based clustering for wireless sensor networks. First, we select the maximum core density anchor node as head to reduce regional d...
