Abstract—Active queue management plays an important role in the performance of all IP based networks and cellular networks in particular where large buffers are deployed in order to absorb bursts resulting from the dynamic nature of the radio channel. Long standing queues building up in large buffers leads to “Bufferbloat”, degrading the performance especially for delaysensitive applications while small buffers may lower the link utilization. This paper proposes a novel AQM algorithm tailored to cellular networks, mainly by utilizing the Quality of Experience (QoE) metric in order to mitigate Bufferbloat and maintain acceptable levels of performance. Simulation results show the proposed algorithm provides a good balance between drops and delay hence successfully maintains expected levels of service. 

Index Terms—QoE, AQM, cellular networks.
