Abstract

The invention provides a positioning method of a mobile terminal and a device thereof. The positioning method of the mobile terminal comprises the following steps of receiving broadcast signals which contain identification information and position information and are sent by each anchor node; according to intensities of the received broadcast signals, determining a distance between the mobile terminal and each anchor node to acquire a distance set; based on the distance set and position information of each anchor node, calculating a first coordinate set of the mobile terminal; according to a sequence of broadcast signal intensities from large to small, selecting the anchor nodes with a predetermined quantity to form at least one triangle or a tetrahedron, and based on a weighted centroid algorithm and the first coordinate set, calculating and acquiring a second coordinate set of the mobile terminal; according to the second coordinate set and a distance from each coordinate in the second coordinate set to a corresponding triangle or tetrahedron vertex in the at least one triangle or the tetrahedron, through the weighted centroid algorithm, calculating a coordinate position of the mobile terminal.

Description

technical field [0001] The present invention relates to the technical field of positioning, and in particular, to a positioning method for a mobile terminal and a positioning device for a mobile terminal. Background technique [0002] Wireless sensor networks are event-oriented monitoring networks. For most applications, the data sensed without knowing the location of the sensor is meaningless. It is one of the most basic functions of the sensor network to determine the location of the event or the location of the node that obtains the message in real time, and it is also the premise of providing the location information of the monitoring event, so the positioning technology plays a key role in the effectiveness of the sensor network application. [0003] However, traditional GPS (Global Positioning System, Global Positioning System) and other positioning systems have poor indoor positioning accuracy and are not suitable for indoor positioning. Therefore, how to improve the...
