Abstract
The position service is becoming more and more important for WSN applications. In order to resolve the problem of low positioning accuracy in WSN, a new positioning algorithm based on virtual beacon nodes is proposed. In this algorithm, the space is divided into several equal areas by anchor nodes; PIT theory is used to estimate the preliminary regional; the best virtual beacon nodes is calculated through the approach degree; finally, an unknown nodes position can be calculated by computing the centroid of the selected anchor nodes. This algorithm adopts the RF signal to locate unknown node.It can not only avoid the overlapped error in a range-based localization algorithm, but also avoid high complexity.
