Embodiment 1
[0071] Embodiment 1 provides a task scheduling method based on dynamic priority in a vehicle-mounted cloud environment, including the following steps:
[0072] Step S1, build a system model, and calculate the completion time of the task through the system model;
[0073] Specifically, step S1 is:
[0074] Assuming that there are multiple vehicles traveling at a constant speed from left to right on a one-way and straight expressway, the driving speed is denoted as v, and there are vehicle-mounted nodes on the vehicles. Define the vehicle-mounted node set N={n 1 ,n 2 ,...,n m}, which means that there are m vehicle-mounted nodes on the expressway;
[0075] The expressway is divided into k sections, denoted as S j (j=1,2...k), the length of each section is denoted as L j (j=1,2...k);
[0076] There is an RSU in the center of the highway, define n i Indicates that the vehicle node is on the road segment S i up, n i to S i The distance to the right border is c i Indicates...
