QoE-Aware Video Delivery in Multimedia IoT Network with Multiple Eavesdroppers

Algorithm 1

: Maximize rate satisfaction algorithm.

	Input: Channel condition and QoS threshold of multi-quality video.
	Output: Optimal beamforming vector and rate satisfaction.
	Step:
(1)	Set the t = 0, beamforming vector satisfies constraint (16d);
(2)	Calculate of each user as follows:
(3)	Solve ;
(4)	Update ;
(5)	;
(6)	;
(7)	;
(8)	If iteration stop. Otherwise, set and go to Step 2.
(9)	Output , and .
