Extending QoS-aware scheduling in ns-3 5G-LENA: a Lyapunov based solution

Abstract

In this paper, we integrate a scheduling solution based on the Lyapunov framework within the ns-3 5G-LENA extension. This approach allows implementing policies that consider the fulfillment of Quality of Service (QoS) requirements, as well as an efficient use of allocated resources. The operation of the proposed solution can be configured from the user file, enabling the use of different strategies. We compare the performance of the proposed scheduler with that exhibited by alternative solutions. The results show that it can guarantee the required bit rate, while yielding a more efficient use of the available resources.
