Abstract

The invention relates to an Internet-of-Vehicles information processing time delay optimization strategy and an implementation algorithm thereof, and the method of one embodiment comprises the steps:building a system model of Internet-of-Vehicles mobile edge calculation, carrying out the quantification of processing time delay under different conditions according to the calculation and storage resource constraints of an edge server in reality, and determining the expression of the processing time delay; determining an optimization objective function to minimize the sum of total time delays ofall vehicles in the whole system; and optimizing the target function by using a quadratic constraint quadratic programming method, and determining an optimal task unloading decision and an optimal service caching decision to obtain the minimum total system delay. The scheme of the embodiment aims to reduce the total time delay of the Internet-of-Vehicles information processing system as much as possible while ensuring the availability of the system.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to an optimization strategy for information processing time delay of the Internet of Vehicles and an implementation algorithm thereof. Background technique [0002] Mobile Edge Computing (MEC) provides IT service environments and cloud computing capabilities at the edge of mobile networks, radio access network (RAN) and close to mobile users. Its goal is to reduce latency, ensure efficient network operations and service delivery, and improve user experience, and is considered one of the key emerging technologies for 5G networks. The Internet of Vehicles (IoV) is an emerging concept in intelligent transportation systems. Due to the integration of advanced communication and information technology in IoV, it helps to solve various traffic and driving problems, thus in a safe and efficient manner. play a vital role in the transportation system. At the same time,...
