An 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 کاملAn Improved DV-Hop Localization Algorithm Based on the Node Deployment in Wireless Sensor Networks
Localization algorithm is an important and challenging topic in Wireless Sensor Networks (WSNs), especially for the applications requiring the accurate position of the sensed information. In this paper, an improved DV-Hop algorithm based on the node deployment was proposed. The proposed algorithm improves the localization accuracy by taking the advantage of the node deployment when computing th...
متن کاملAn improved node localization algorithm based on DV-Hop for wireless sensor networks
Sensor node localization is the basis for the entire wireless sensor networks. Because of restricted energy of the sensor nodes, the location error, costs of communication and computation should be considered in localization algorithms. DV-Hop localization algorithm is a typical positioning algorithm that has nothing to do with distance. In the isotropic dense network, DV-Hop can achieve positi...
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 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...
