Abstract

Ultrawideband (UWB) is an emerging technology that is expected to achieve high data rate with low-power transmission and to enable quality-of-service (QoS)-based multimedia services over wireless personal area networks (WPANs). Currently, WiMedia alliance proposes the physical layer and medium access control (MAC) layer standards for WPANs. Although WiMedia MAC defines the QoS signaling mechanism, it does not specify the resource-allocation algorithm that will eventually provide the QoS guarantee. To address this issue, we first propose a novel traffic predictor for real-time variable bit rate (VBR) videos. Based on the proposed predictor, we then present a dynamic resource-allocation (DRA) algorithm to support real-time VBR video transmission over WiMedia-based WPANs. Simulation results indicate that the proposed traffic predictor and DRA algorithm significantly outperform other existing schemes.
