A new approach for finding minimum delay control centers of Control networks

A Control network denotes a group of devices to monitor, control, communicate and manage system operation. In a wide area control network, decision making location is known as control center. The communication delay (latency) between a node and a control center in a control network has been characterized by network topology, transmission media characteristics and location of control center. The aim of this investigation is to propose an algorithm which tries to find an appropriate control center location such that all nodes´ latencies are minimized and equalized. The simulation results show that if a control center with determined latency limitation exists, the proposed algorithm can locate it. Otherwise, the entire control network can be partitioned into multiple areas such that the latency limitation in each area has been satisfied.
