Quality-of-service provisioning to assured service in the wireless Internet
Abstract: A major challenge in establishing the wireless Internet is provisioning of quality of service (QoS) to different Internet applications. In this paper, we propose a vertically layered scheme to provide QoS for the assured service with a committed information rate (CIR). By controlling the delay and packet loss performance seen from the transport layer, we can achieve the required CIR. Based on the proposed scheme, the resources needed to meet the rate requirement of the assured service can be determined. The resource allocation problem is also formulated as an optimization problem. Numerical results demonstrate that efficient resource utilization can be achieved.
