In this paper, a reachability-guaranteed approach for reducing broadcast storms in MANET is proposed. The approach is based on location awareness, which means each node in the network needs to equip the positioning device like GPS and exchanges location information in the HELLO message with its neighbors. Three mechanisms are included in the proposed(More)
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 multimedia 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, 802.16 QoS(More)
A novel model namely Extended Real-Time Synchronization Model (E-RTSM) for modeling SMIL2.0 synchronization behaviors is proposed in this paper. E-RTSM deals with schedule-based synchronization as well as event-based synchronization in SMIL2.0. Converting of the temporal relationship of a SMIL2.0 document to E-RTSM is presented. Moreover, design of the(More)
Clustering is an important technique in mobile ad hoc networks to provide a framework for management and reduce the overhead of route acquisition. Many clustering techniques had been proposed in the literature, but few of them had considered the status of network from the aspect of stability. In this paper, a stability-based clustering (SBC) technique is(More)
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)
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)
