A QoS-aware Bandwidth on Demand Assignment Mechanism in a GEO Satellite System

This paper deals with the problem of the design of a control-predictive based Demand-Assignment Mechanism for a satellite network guaranteeing a target Quality of Service (QoS) to Internet traffic, while efficiently exploiting the air interface. The proposed mechanism is in charge of dynamically partitioning the uplink capacity among the connections in progress in the considered spot-beam. Such a partitioning is performed aiming to match the QoS requirements of each connection and to maximize bandwidth exploitation. A Control Theory approach is adopted to address the problem of the delay between the bandwidth request and bandwidth assignment, and the signaling overhead caused by control messages.
