On a throughput-efficient look-forward channel-aware scheduling

In this paper, we first present a detailed analysis for studying the effect of changing the time difference between two successive channel predictions on the outage probability and the system´s reliable transmission rate. Secondly, we propose a low complexity heuristic scheduling algorithm that utilizes long-term ray tracing channel predictions to improve the system throughput in wireless networks. The proposed heuristic algorithm achieves almost identical throughput as the optimal scheduler and outperforms traditional channel-aware schedulers in terms of system´s average throughput with low computational cost. The scheduler´s performance is tested in the presence of Rayleigh fading and log-normal shadowing effects.
