Embodiment Construction

[0037] In order to facilitate those skilled in the art to understand the technical content of the present invention, the content of the present invention will be further explained below in conjunction with the accompanying drawings.

[0038] The car networking scene applied by the present invention is as follows: figure 1Shown: The network system consists of a macro base station with a mobile edge computing server and vehicles connected to the macro base station. Among them, the macro base station can provide communication services and computing services for vehicles connected to itself. The communication resources of the macro base station are divided into K sub-channels, and these K sub-channels are orthogonal to each other without interference. A set of subchannels is denoted by K={1,2,...,K}. The vehicle set is N={1,2,...,N}. It is assumed that each vehicle will request the wireless VR service s from the macro base station, and the wireless VR service s can be arbitrari...

Abstract

The invention discloses a method for joint decision-making of resource allocation and unloading ratio, which is applied in the technical field of vehicle-mounted wireless communication. Facing the decision-making problem of communication resources, computing resource allocation, and unloading ratio, the present invention first allocates a communication sub-channel for each vehicle, determines the optimal unloading ratio and optimal computing resource allocation at this time according to the communication resource allocation, and then calculates the optimal unloading ratio and computing resource allocation. Evenly allocated for comparison, further modify the current computing resource allocation and unloading ratio, so that the task completion time is always kept at a minimum; finally traverse the task completion time of the vehicle, if there are still assignable channels, then assign a new one to the vehicle with the longest completion time Communication sub-channels, and update computing resource allocation and unloading ratio, the method of the present invention can complete the VR service requested by the vehicle in a relatively short time.

Description

technical field [0001] The invention belongs to the technical field of vehicle wireless communication, and in particular relates to a wireless VR service unloading ratio and resource allocation technology. Background technique [0002] The Internet of Vehicles (IOV), which connects vehicles, is emerging with the development of computing and communication technologies. The demand for rich multimedia services in vehicular networks continues to increase, which has attracted great attention from the industry and academia (references: Z.Su, Y.Hui, Q.Yang, "The next generation vehicular networks: a content-centric framework", IEEE Wireless Communications, vol.24, no.1, pp.60-66, 2017.). On the other hand, the computing resources of the vehicle itself are insufficient, so it is unrealistic to rely solely on the vehicle to complete the calculation of the business; moreover, the business requested by the vehicle generally has the requirements of low delay and high reliability. Serv...
