Failure-Aware and Delay-Predicted Multipath Virtual Queue Scheduling for Multimedia Transmission in Edge IoT

Algorithm 1

Transmission factor estimation.

(1)	Initialize: subflow set , packet-loss interval set , the packet-loss time , the last packet-loss time .
(2)	while transmission not end do
(3)	for each do
(4)	if dropping then
(5)	Get new ;
(6)	Update according to equation (5)
(7)	if packet-loss occurs in then
(8)	ifthen
(9)	Get the packet-loss time
(10)	Add to ;
(11)	else
(12)	;
(13)	Get the packet-loss time ;
(14)	Calculate ;
(15)	Add to
(16)	if receive new ACK on subflow then
(17)	Get new , ;
(18)	;
(19)	Updated according to equation (3)
(20)	Calculate according to equation (2);
(21)	Calculate according to equation (4);
(22)	Calculate according to equation (12);
(23)	Update according to equation (1);
