A Time-Delay-Bounded Data Scheduling Algorithm for Delay Reduction in Distributed Networked Control Systems

Algorithm 1

Scheduling mechanism in feedback channel for distributed NCSs.

	Input: an existing transmission set ; a new data packet with .
	Output: a new transmission set .
(1)	Calculate the time-delay upper bound with Theorem ?? for the data packet;
(2)	Calculate transmission priority with , i.e., ;
(3)	Compare calculated to of in the set;
(4)	if calculated for then
(5)	Insert into the end of set , go to step 10;
(6)	else
(7)	Calculate information execution time using equations (10)–(18);
(8)	Insert into set according to in an increasing order;
(9)	end if
(10)	Calculate the actual packet execution time using equation (18);
(11)	Scheduling operation according to the order of transmission set ;
