Optimization Strategy of Task Offloading with Wireless and Computing Resource Management in Mobile Edge Computing

Algorithm 1

Semi-distributed TOWCRM Algorithm.

Stage 1: at UEs side

1: for each base station do

2: for each device do

3:  improved graph coloring algorithm

4:  equation (28)

5:

6: end for

7: end for

8: if then

9: send an offloading request

10: else

11: send NULL

12: end if

Stage 2: at the MEC side

13: Wait until all requests are accepted

14: for do

15: , .

16: set

17: end for

18: step 3; step4

19: equation (29)

20: let K be the set of UEs that the server accepts requests but does not accept offloading

21: while do

22: 

23: 

24:  step 3; step 4; step 19

25: if then

26: 

27: else

28: 

29: 

30: 

31: end if

32: 

33: end while

34: The MEC server forms RB allocation strategy and computing resources and starts to send offloading decision to UEs
