AI Technical Summary

Benefits of technology

This technology helps identify missing or incorrect connections within networks quickly without recalculating them manually. By calculating differences across these connections with respect to their own baseline distances (their corresponding known ones), it becomes easier to fix any issues related to those connected components. Overall, this technique enhances the performance and reliability of systems like wireless communication devices such as base stations.

Problems solved by technology

This patents describes different ways to improve the performance of Wireless Sensor Networks (WSN). These techniques include improving signal reception at anchoring points or reducing energy usage during communication while also optimizing data transmission speed. Additionally, there has been an increasing interest towards developing 3D sensory networks where objects like furniture may move around without affecting their orientation. Existing solutions involve expensive equipment and complicated procedures.

Abstract

The invention relates to a three-dimensional positioning method, device and system based on a wireless sensor network and a computer readable storage medium. The method comprises the following steps of respectively computing a reference hop distance of each anchor node in the wireless sensor network; computing an average value of the reference hop distances of the anchor nodes in the wireless sensor network, and acquiring a correction hop distance of each anchor node according to the average value; and acquiring minimum hop count of an unknown node and the anchor nodes in the wireless sensor network, and determining positioning coordinates of the unknown node according to the correction hop distance and the minimum hop count. According to the three-dimensional positioning method based on the wireless sensor network, the average value of the reference hop distances of the anchor nodes is computed, the correction hop distance of each anchor node is acquired, and the positioning coordinates of the unknown node are determined, so that an accidental error between different anchor nodes can be effectively eliminated, and the accuracy of positioning the unknown node in the three-dimensional positioning is improved.
