Resource Management Methods Based on Control Theory for Communication Networks:

Optical Grid and Cognitive Wireless Networks

Abstract

Recently, communication technologies for reliable remote control have become indispensable, and many communication technologies based on control theory have attracted considerable attention. In particular, networked control that considers the packet loss and transmission delay, and control-theory-based data transmission that considers the quality of the service of data transmission have been studied actively. In this paper, we introduce resource management technologies based on control theory for optical grids and cognitive wireless networks. For optical grids, the resource management technologies utilize PID control and model predictive control so that both computer resources and wavelength resources are utilized effectively. For cognitive wireless networks, on the other hand, the resource management technologies adjust the transmission power to utilize wireless resources effectively by utilizing PID control and model predictive control. In terms of the technologies, we explain how each network is modeled and how PID control and model predictive control are utilized.
