Description
Summary:This paper describes a scheduling strategy for a real time distributed system based on modifying the transmission frequency of nodes in a communication network. Scheduling is critical as it impacts the system performance due to limited computing resources. This work presents a linear time invariant model based on the frequency transition of nodes in distributed system. In this model a Linear Quadratic Regulator (LQR) controller is designed to schedule the transmission frequency of nodes. The controller assigns the transmission frequency into a region with minimum and maximum bounds intended to satisfy the network’s utility. A 2DOF helicopter simulation shows the effectiveness of this scheduling strategy.
