Max-min rate control on traffic in broadband multibeam satellite communications systems

This letter presents a new method of rate control on the incoming traffic in broadband multibeam satellite communications systems. In this method, the rate control problem is formulated as a max-min optimization with stability, average delay, and beam-sharing constraints. For this nonlinear and nonsmooth optimization problem, we translate it to a linear programming problem and thus easily get its optimal solution. Our analysis and numerical results show that the proposed method outperforms the existing in the literature in terms of both system throughput and user-level admission capability.
