Abstract

This paper proposes a preemptive scheduler that takes back resource previously allocated to best effort traffic users for minimizing the drop rate of delay constrained traffic users. An online implementation with low complexity is proposed, where the channel and QoS aware preemption metric takes into account the benefit for the drop rate of the delay constrained traffic and the cost on the fairness of the pre-allocated best effort traffic. By inverting the state of art order of the allocation of delay constrained and best effort traffic, we show that the fairness-throughput tradeoff curve of the best effort traffic is improved with no degradation on the drop rate of the delay constrained traffic. This scheduler is particularly relevant in cellular networks mixing safety-related and non-safety related (data) traffic, such as LTE for trains, tram, buses or cars.
