In both the approaches multiple servers simultaneously serve one requesting ...

MDVT converts a single description encoded video into two or more descriptions at an intermediate node in the network. The objective of our MDVT approach is to adapt the ...

Our approach is based on joint optimization of the application layer, the data link layer and the physical layer. For this, key parameters from these three ...

We combine both ideas in a downlink multicarrier transmission scheme where ...

One of the key challenges in CLO is the exchange of parameters between optimizer and layers. In this paper a model-based approach is presented that drastically reduces the amount of parameters that are to be exchanged. The optimizer
