Abstract

In order to achieve high data rates, future mobile networks employ complex algorithms in the physical and MAC layers. Previous studies have shown relevant interactions between these algorithms and transport and application layer mechanisms. An efficient design of lower layers requires consideration of higher layers, given that the service quality experienced by the user is the ultimately relevant performance metric. In this paper, we give a brief overview of different approaches that allow for the joint evaluation of PHY, MAC, transport, and application layer. We then focus on the integration of virtual machines into our system level simulation tool. This approach enables us to evaluate the application performance even if the entire setup was too slow to run in real-time. With this approach, evaluating the application performance can be done by both deriving objective performance metrics and playing back traces (e.g. video) later on.
