A control based Traffic Controller in wireless and satellite downlink channels

This paper presents an innovative control based Traffic Controller which provides at sharing a single resource, namely the available bit rate, among a set of IP flows characterized by different Quality of Service (QoS) requirements. The main novelty behind the proposed Traffic Controller is that it relies on an original control based approach which exploits a closed-loop architecture and a fuzzy tuner. Simulation results demonstrate that such Traffic Controller outperforms a well known Traffic Controller (namely the one based on the presence of Dual Leaky Buckets and Earliest Deadline First scheduling algorithm).
