Three-dimensional space intelligent positioning and distributed edge computing support method of Internet of Things

Abstract

The invention discloses a three-dimensional space intelligent positioning and distributed edge computing support method for the Internet of Things, and the method comprises the following steps: acquiring energy consumption of each anchor node and distance information between each anchor node and Internet of Things equipment, and constructing an available anchor node set for each piece of Internet of Things equipment; according to the included angle relation between the anchor nodes, selecting four non-coplanar anchor nodes from the available anchor node set to construct a positioning unit set of the Internet of Things equipment; solving the positioning coordinates of the Internet of Things equipment through the anchor node information in the positioning unit set, and solving the position of the target Internet of Things equipment through the mean value of multiple times of positioning; acquiring positions and task request types of all the Internet of Things devices, dynamically executing path planning by using an unmanned aerial vehicle base station carrying an edge server so as to process requests of the plurality of Internet of Things devices, and determining an unloading decision; enabling the unmanned aerial vehicle to navigate according to the optimal path plan and get close to the Internet of Things equipment, and enabling the Internet of Things equipment to carry out edge calculation unloading.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, and relates to a three-dimensional space intelligent positioning and distributed edge computing support method of the Internet of Things. Background technique [0002] Driven by the Internet of Things (IoT) technology, more and more smart devices are connected to the network and are widely used in various fields of production and life, such as performing environmental monitoring, target tracking, and risk warning. In many cases, these IoT devices are widely deployed in unattended or even challenging areas, such as forests, deserts, and military areas, and need to be constantly moving to perform established tasks, such as object tracking and identification. However, many low-cost IoT nodes cannot afford the high cost of global navigation satellite systems (GNSSs) receivers, and cannot effectively use global navigation and positioning systems such as GPS, Beidou navigation system, et...

Problems solved by technology

In some challenging regional scenarios, the above-mentioned technical solution may have sparse distribution of ground communication infrastructure and cannot provide reliable communication for IoT nodes. Therefore, the direct cloud offloading of the four computing offloading modes in this patent cannot achieve computing uninstall request
