Abstract: This paper describes a novel control-theoretic distributed multicast congestion control scheme, called self-tuning proportional integrative plus derivative (SPID) controller. The control parameters can be designed to ensure the stability of the control loop in terms of source rate. The distributed explicit rate SPID overcomes the vulnerability that suffers from the heterogeneous multicast receivers. The SPID controller is located at the multicast source to regulate the transmission rate. Simulation results demonstrate the efficiency of the proposed scheme in terms of system stability and fast response, low packet loss, and high scalability.
