(a) Local execution of all tasks;
(b) All tasks are executed on the MEC server and are based on task priority;
(c) All tasks are executed on the MEC server and are not based on task priority.
3.1 Average Execution Time of Different Algorithms with High Priority
Firstly, we compare the average execution time of various algorithms for high-priority
tasks as the number of tasks increases. As can be seen from Fig. 4, the average
execution time of high priority increases slowly. Algorithms (a), the average execution
time of high priority is larger than that of priority-based task migration model from the
beginning. Algorithms (b), although the high-priority delay increases, it is not very
