Obtaining More Realistic Cross-Layer QoS Measurements: A VoIP over LTE Use Case
We introduce a real-time experimentation testbed in this paper which enables more realistic analysis of quality of service (QoS) in LTE networks. This testbed is envisioned for the improvement of QoS and quality of experience (QoE) through the experimentation with real devices, services, and radio c...

| description | We introduce a real-time experimentation testbed in this paper which enables more realistic analysis of quality
of service (QoS) in LTE networks. This testbed is envisioned for the improvement of QoS and quality of experience (QoE)
through the experimentation with real devices, services, and radio configurations. Radio configurations suggested in the
literature typically arise from simulations; the testbed provides a real and controlled testing environment where such configurations can be
validated. The added value of this testbed goes a long way not only in the provision of more realistic results but also
in the provision of QoS and QoE cross-layer measurements through the correlation of information collected at different
layers: from service and IP levels to radio and protocol parameters. Analyzing the interlayer dependencies will allow
us to identify optimal settings for the radio access network and service parameters. This information can be used to
suggest new cross-layer optimizations to further improve quality of experience of mobile subscribers. As a use case, we
examine VoIP service over LTE, which is currently an open issue. |
