Dynamic resource allocation method and device in multi-unmanned aerial vehicle assisted industrial scene

Abstract

The invention provides a dynamic resource allocation method and device in a multi-unmanned aerial vehicle assisted industrial scene. The method comprises the following steps: constructing a resource allocation model by taking a queue time delay threshold deviation probability of ground equipment and unmanned aerial vehicles as a constraint condition; using a Lyapunov stochastic optimization method to deform the resource allocation model; and solving the deformed resource allocation model by using a generalized boundary decomposition method to obtain a resource allocation scheme of the multiple unmanned aerial vehicles. The method and the device are used for overcoming the defect that in the prior art, only average indexes such as average delay and stability of dynamic queues are considered during resource allocation, and the high-reliability and low-delay scene requirements of key applications cannot be met, and stable data transmission and calculation under the multi-time-slot condition are achieved on the basis of minimizing the sum of transmitting power of ground equipment.

Description

technical field [0001] The present invention relates to the technical field of dynamic resource allocation in industrial Internet scenarios, and in particular to a method and device for dynamic resource allocation in multi-UAV assisted industrial scenarios. Background technique [0002] Ultra-reliable low-latency communications (URLLC), as one of the three major scenarios of 5G, will play a pivotal role in the future of 5G and 6G. With the accelerated pace of intelligent manufacturing and the drive of big data demand in industrial scenarios, the amount of data in industrial Internet scenarios shows a trend of soaring. However, the current contradiction between the surge in data volume and the shortage of computing resources affects the performance of users. For some intensive application scenarios, such as IoT devices for analyzing industrial big data, their limited battery power consumption is not enough to support huge Calculations. At the same time, ensuring the reliabi...
