A distributed flow control for mission-oriented wireless multimedia networks using cooperative communications

This paper proposes a novel and efficient distributed flow control for wireless multimedia networks using cooperative communications, based on the Proportional Integral (PI) controllers. The control parameters can be designed to ensure the stability of the control loop in terms of source rate. The distributed explicit rate controller is located at the wireless multimedia sensor source to regulate the transmission rate for mission. We further analyse the theoretical aspects of the proposed algorithm. Simulation results demonstrate the efficiency of the proposed scheme in terms of system stability, fast response, and high efficiency for mission-oriented multimedia systems. Simulation results show that the performance of our scheme is improved more than 10% when compared with other method.
