BP Network Control for Resource Allocation and QoS Ensurance in UAV Cloud

Algorithm 3

Algorithm of MQEB.

(1) , initialize .

(2) Start TS-LOOP.

(3)  For .

(4)   Sample the actually ith HQ delay .

(5)   According Algorithm 1, get the and the number of time slots .

(6)   Distribute slots for ith HQ.

(7)  End For.

(8) End TS-LOOP.

(9) Start CW-LOOP.

(10)   Sample the actual jth SQ delay , the accessing probability , and queueing length .

(11)   Construct and SOP as (24).

(12)   Solve SOP according to Algorithm 2, and get the solution .

(13)   Distribute slots for all SQ.

(14)  For .

(15)   Sample the actual accessing probability and scale factor as inputs. According to Algorithm 1, get and the scale factors .

(16)   Adjust scale factor for jth SQ.

(17)  End For.

(18) End CW-LOOP.

(19) , go to step 1.
