A cooperative ratio-based scheduling scheme with minimal signaling that enhances network throughput and fairness in a wireless ad hoc network is presented in this paper. Throughput maximization problem under fairness constraint in a finite horizon is formulated as a novel multi-window optimization problem. Through analysis users' thresholds are shown to be time variant for throughput maximization with fairness in each time window. Simulation results clearly show that compared with non decision-based strategy, Simple Ratio-based scheme (SR) achieves within 1.6% of the global optimal value in terms of throughput and is scalable in terms of the number of nodes.
