A Mobile Anchor Node Positioning Algorithm for WSN in Three-dimensional Space

Abstract

In wireless sensor network, in order to effectively reduce the influence of the complex environment in node localization accuracy, based on trilateral plane positioning algorithm, this paper proposes an algorithm about the mobile anchor node and fuzzy information (Mobile Anchor Node Localization on Fuzzy Information, referred to as MANLFI) to achieve a node localization in three-dimensional space. By constantly updating the speed and position of the anchor node, we measure the direction angle and pitch angle between anchor nodes and other nodes to achieve node localization. In this paper, when nodes are located by algorithm, which will act as static anchor nodes to attach other nodes. Experiment shows that, compared with APIT-3D, the bounding cube algorithm of MANLFI improves the localization accuracy of nodes and the stability of network and with less delay.
