Abstract

The invention discloses a method and device for optimal scheduling of Internet of Vehicles resources based on successive convex approximation. The method introduces multi-data stream carrier aggregation technology, and processes the resource allocation process in a unified manner under the target of maximizing the transmission rate of the downlink communication network of the Internet of Vehicles. Distributed resource scheduling is realized through the upper bound algorithm, convex optimization theory and dual technology; because the present invention considers that vehicle users can receive data transmitted by different base stations at the same time, the system spectrum utilization rate is greatly improved, and the proposed distributed resource optimization The scheduling algorithm, after several iterations, has a fast convergence speed, and the optimal power allocation scheme obtained has certain practicability. It is suitable for a series of existing vehicle networking scene architectures, and can guarantee the speed of users while optimizing the total utility of the network. need.

Description

technical field [0001] The invention belongs to the field of wireless communication networks, and in particular relates to a method and device for optimal scheduling of resources of the Internet of Vehicles based on successive convex approximation in a communication system of the Internet of Vehicles. Background technique [0002] Since the 21st century, with the rapid increase in the penetration rate of automobiles, road congestion has become more and more serious, and traffic accidents have also increased frequently. Intelligent transportation, alleviating congestion, reducing safety accidents, and making travel more convenient and reliable have increasingly become the focus of attention. Therefore, the Intelligent Transportation System (ITS) came into being to provide technical support for solving traffic problems, and ITS has the characteristics of high efficiency, real-time, and large management range. With the rapid development of wireless communication technology and...
