The Impact of End-to-end vs. Link-layer Mechanisms on Real-Time Performance over Wireless Links

We evaluate selected research proposals towards the efficient real-time QoS management over wireless links. We mainly focus on real-time performance of link-and transport-level mechanisms that bind operationally wired and wireless links. Employing a new metric for the evaluation of real-time performance we demonstrate that there are occasions where increased goodput does not correspond to real-time performance gains. In the sequel, we exploit further the potential of transport layer approaches
