In this paper, the Quality of Service (QoS) for
multimedia traffic of the Medium Access Control (MAC) protocol for Ultra Wide-Band (UWB) networks is investigated. A protocol is proposed to enhance the network performance and increase its capacity. This enhancement comes from using Wise Algorithm for Link Admission Control (WALAC). The QoS of multimedia
transmission is determined in terms of average delay, loss
probability, utilization, and the network capacity. In addition,
a new parameter is aroused for the network performance.
