Ultra-WideBand (UWB) networks are expected to support a wide range of communication-intensive, real-time multimedia applications. One of the key issues in UWB networks is optimization of Quality of Service (QoS) parameters. To meet the QoS demands of each UWB user and maximize the overall network throughput, several technical aspects shall be concerned, e.g. physical layer transmission format, multi user access format and routing solution. In this paper, a centralized Impulses Radio Ultra-WideBand (IR-UWB) multi user system which contains one Network Coordinator (NC) is considered.
