Embodiment Construction

[0056] like Figure 1-2 As shown, the method for deploying unmanned aerial vehicles to enhance base station communication based on the physical gravity model provided by the present invention is described in detail as follows:

[0057] In practical references, drones are relays between base stations and users. The UAV communicates with the base station using cellular data, and the UAV communicates with the user using WiFi working at 2.4GHz. This method is firstly based on the idea of ​​a division, cutting the hotspot area to make the problem smaller. Then introduce the model of physical force to simulate the effect of force, and regard the user as a negatively charged particle, and the drone as a positively charged particle. The user acts forcefully on the drone until the drone reaches the equilibrium point. This method can not only be used to assign drones to a single block, but also allows the user to move the position of the drone in subsequent steps. At this time, you a...

Abstract

The invention is applicable to the technical field of wireless communication, and provides a method for deploying an unmanned aerial vehicle to enhance base station communication based on a physical gravity model. The method comprises the following steps: S1, dividing a hotspot area by using a KDivide method in a horizontal and vertical alternate cutting manner, so that the user number in each divided small square meets the capacity of a single unmanned aerial vehicle; S2, judging whether the unmanned aerial vehicle needs to be allocated to the divided small square by calculating an ObjectiveFunction, if yes, allocating the unmanned aerial vehicle, and executing the next step, or otherwise, not allocating the unmanned aerial vehicle; S3, positioning the location of the unmanned aerial vehicle for an uncovered user according to EMech; and S4, merging each two of the divided small squares by using a RMerge reversal step until the divided small squares are merged into a square of an initial hotspot area. By adoption of the method, the data efficiency that can be provided by a base station is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a method for enhancing base station communication by deploying drones outdoors based on a physical gravity model. Background technique [0002] With the continuous development of drone communication technology, the use of drones as air mobile base stations provides a solution to alleviate the overload of base stations in a short period of time, which is the focus of next-generation network providers. Specifically, UAVs can act as relays between ground users and ground base stations to meet the growing business needs in hotspots. Compared with traditional ground base stations, UAVs are more flexible, can be allocated according to user needs, and can be placed conveniently and quickly. At the same time, due to the flying height of the UAV, the shading of ground obstacles and the multipath effect are small, the probability of the line-of-sight connection ...
