Abstract :
The next generation of wireless mobile networks will apply IP to offer a mixed set of services, varying from real time voice-over-IP and videoconferencing, to best effort transmission of E-mail messages. This paper investigates the coupling between the queuing mechanism on the IP and data link layer to be able to offer end users a guaranteed QoS. Priority scheduling is investigated as a means to directly map the QoS levels from the network layer and the MAC layer. A novel scheduling strategy, which introduces a control unit, and synchronises QoS requirements on the IP network layer and the radio layer, is presented as well. The combination of information from different layers in the protocol stack allows for a more optimised and accurate control of the traffic flows with different QoS requirements
