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)
Zone routing protocol provides a flexible solution for discovering and maintaining routes in the MANET. By adopting the idea of Fisheye state routing in TRP, a more efficient protocol called fisheye zone routing protocol (FZRP) was proposed in the paper. FZRP provides the advantage of a larger zone with only a little increase of the maintenance overhead.(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)
