— Video traffic, especially MPEG-4 streams, is envisioned to be a dominant traffic type in the IEEE 802.15.3 high-rate wireless personal area networks (WPANs). The unique hierarchical structure of MPEG-4 streams calls for special measures at the MAC layer, in order to improve the quality of service (QoS). In this paper, we propose a frame-decodability aware(More)
— The emerging high-rate wireless personal area network (WPAN) technology is capable of supporting high-speed and high-quality real-time multimedia applications. In particular, MPEG-4 video streams are deemed to be a widespread traffic type. However, in the current IEEE 802.15.3 standard for media access control (MAC) of high-rate WPANs, the implementation(More)
Increasing deployment of computer systems in critical applications has made study and quantifiable analysis of these systems as an important issue. This analysis can either be done on real system or by developing analytic models. First approach is less desirable, since such an analysis is typically done in a post-facto manner after any problem has occurred.(More)
