Abstract

The invention discloses an internet of vehicles resource optimization scheduling method based on successive convex approximation and a device. The method introduces a multi-data stream carrier aggregation technology, maximizing an internet of vehicles downlink communication network transmission rate and allocating resources in a unified manner; further, distributed resource scheduling is realizedthrough an upper bound algorithm, a convex optimization theory and a duality technology. Considering that vehicle users can receive data transmitted by different base stations at the same time, the method improves the system spectrum utilization ratio greatly, further, after multiple times of iteration of the mentioned distributed resource optimization scheduling algorithm, the convergence speed is fast, and the obtained optimal power allocation solution is practical to a certain degree, is applicable to a series of existing internet of vehicles scenario architectures, optimizes total networkutility and meets rate requirements of users.

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...
