Buffer-Aided Relay Selection for Packetized Predictive Control

In wireless communications, relay selection is very important to enhance the communications between the resource and destination. However, only transmission coefficients are considered in traditional relay selection. In this paper, we consider the relay selection in wireless packetized predictive control (PPC) systems, where our goal is to select the relay nodes by jointly considering communication sub-system and control sub-system. To achieve this goal, we propose a buffer-aided relay selection method, in which both communication performance and control performance are jointly optimized. Simulation results show the performance of our proposed method.
