An Improved Weighted Centroid Localization Algorithm
As one of the most important applications of wireless sensor network, positioning technology has become a extremely hot research filed. Taking into account of the position of beacon nodess, they make an effect on the positioning accuracy of unknown nodes. Therefore, in this paper, it proposes a new weighted centroid localization algorithm based on the traditional algorithm. For the selection of...
متن کاملAn Improved Centroid Localization algorithm for WSN
In wireless sensor networks (WSN) research area, node localization is one of the most important techniques. An improved Centroid localization algorithm is analyzed and an improved Centroid algorithm with selective anchor node localization algorithm (CSA) for WSN will proposed in this paper. The key point of the algorithm is the most discrepant estimation nodes are selected by the nearest refere...
متن کاملNode Degree based Improved Hop Count Weighted Centroid Localization Algorithm
Hop-count based weighted centroid localization is a simple and straightforward localization algorithm, which uses anchors with known positions and the hop count to these anchors to estimate the real position of nodes. Especially in sensor networks, where energy restrictions prevent more complex algorithms, this fast and simple algorithm can be used. Unfortunately the localization error of the a...
متن کاملImproved Weighted Centroid Localization Algorithm Based on Rssi Differential Correction
Node localization is one of the key technologies of wireless sensor networks (WSN). Due to the indoor environment requires a high positioning accuracy, an improved algorithm based on RSSI is put forward. In terms of RSSI ranging, the error correction coefficient received from self-correcting locator beacon nodes, and then had been applied to distance solving from unknown nodes to the beacon nod...
متن کاملPrecision optimization of node localization centroid algorithm for WSN
Aiming at the problems that the traditional centroid algorithm in WSN node positioning precision is not high and the error is very large, this paper proposed a adaptive centroid algorithm based on weighted factor, first of all, determined the weighting factor according to the influence of different beacon node to the unknown node, with weights to reflect the impact of each beacon nodes for cent...
