—For mobile multi-hop wireless network, IEEE 802.16j/MR network can not only supply large area wireless deployment, but also provide high quality network service to mobile users. In this paper, we will be focusing on QoS supporting for mobile users in the IEEE 802.16-MR network. The probability of a mobile user who visits a RS is known beforehand. With the(More)
SUMMARY As one of the promising techniques in Broadband Wireless Access (BWA), IEEE 802.16 also namely WiMax provides wide-area, high-speed, and non-line-of-sight wireless transmission to support multi-media services. Four service types are defined in the specification of IEEE 802.16 for QoS support. In order to achieve end-to-end multimedia services ,(More)
In this paper, an authoring tool named SMILAuthor for SMIL-based multimedia presentations is proposed. SMILAuthor adopts standard SMIL language as the format of the presentation to generate reusable and easily accessible presentations. Moreover, powerful editing functions such as cut, copy, and paste are supported by the system in a timeline-based manner.(More)
In this paper, we investigate the characteristics of IEEE 802.16 and conclude that it is better to equip BS (base station) and SS (subscriber station) with Layer 3 functionality. Therefore, an 802.16 network can act as the backbone network of different subnets for better deployment. Based on the two IEEE Specifications, 802.16-2004 and 802.16e, we propose(More)
— Distributed multimedia presentation enables users to view a multimedia presentation in the distributed manner, in which the objects of the presentation are located in remote sites. User-interaction provi des the viewer with convenient viewing styles like fast forward and fast backward for a presentation, but it also introduces complexity to the(More)
