Joint Optimization of Offloading and Resource Allocation for SDN-Enabled IoV

Algorithm 1

A offloading decision making algorithm based on PSO.

Input:

 The input parameters of particle swarm:

Output:

1: Fordo

2: For each do

3:  Initialize the velocity position of particles

4: End for

5: In Algorithm 2, we obtain then record the current position and fitness as particle’s individual extreme option and value .

6: Record the smallest fitness and the corresponding position as .

7: While the number of iteration steps is not 0 do

8:  Fordo

9:   Update the velocity of particles using Equation (16)

    Update the position of using Equation (17)

    Evaluate fitness of particle using Equation (14)

10:   Ifthen

12:   End if

13:   Ifthen

14:     =

15:   End if

16:  End for

17: End while

18: End for

19: Return
