    Design of Cross-Layer QoS Scheme in WiMAX Networks

    The IEEE 802.16 working group developed the WMAN to achieve Broadband Wireless Access (BWA). IEEE 802.16 is a high-speed wireless network technology that can provide multimedia services and Quality of Service (QoS) support for multi-level service types. The IEEE 802.16 standard provides QoS support for four service types: UGS, rtPS,...

    A Clustering Technique of Load-Based Power Saving in the IEEE 802.16e Network

    Previous works in IEEE 802.16e power saving mainly focused on standard Type I or Type II power saving class. The limitation of adopting Type I or Type II was discussed in the authors' previous work, and the idea of applying traffic modeling and measurement called Load-Based Power Saving (LBPS) was...

    Adaptive Zone-Based Bandwidth Management in the IEEE 802.16j Multi-Hop Relay Network

    By comparing with the characteristics of the traditional mobile Quality-of-Service mechanisms, the idea of zone-based bandwidth allocation for mobile users in the IEEE 802.16j multi-hop relay network (IEEE 802.16-MR) is proposed in the paper. The zone of a mobile user includes the current relay station and its neighboring relay stations...

    A Zone-Based Bandwidth Allocation Protocol in WiMAX Multi-Hop Relay Networks

    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, the authors will be focusing on QoS supporting for mobile users in the IEEE 802.16-MR network. The probability of a mobile...

    Effective Topology-Aware Peer Selection in Unstructured Peer-To-Peer Systems

    Peer-to-Peer systems form logical overlay networks on top of the Internet. Essentially, peers randomly choose logical neighbours without any knowledge about underlying physical topology. This may cause inefficient communications among peers. This topology mismatch problem may result in poor performance and scalability for Peer-to-Peer systems. A possible way to improve...

    Volatility Spillover: Dynamic Regional And World Effects

    This paper investigates the dynamic nature and determinants of volatility spillovers from European region and world to the five emerging European equity markets that are not members of the European Monetary Union. Using a multi-factor model with time-varying loadings estimated in three stages, the results show significant world and regional...

    System-on-Chip Architecture for Speech Recognition

    In this paper, the authors proposed a System-on-Chip (SoC) architecture for speech recognition which is speaker dependent. The feature extraction bases on LPC (Linear Predictive Coefficient)- cepstrum coefficients, and template matching employs Hidden Markov Models (HMM). It does not aim to offer a sophisticated solution but rather a high speed...

    Adaptive Power Saving Strategy Based on Traffic Load in the IEEE 802.16e Network

    Previous works in IEEE 802.16e power saving mainly focused on standard Type I or Type II. The limitation of adopting Type I or Type II is discussed in the paper, and the idea of applying traffic modeling and measurement mechanisms called Load-Based Power Saving (LBPS) is proposed. The base station...

    Fairness Index Based on Variational Distance

    Fairness index among competing hosts in communication networks is an important system measurement. Several fairness index measurements have been proposed in the technical literature. However, most of these measurements, such as the max/min fairness index and Jain's index, reflect only a long-term average fairness of the system. Instantaneous fairness property...

    Tree-Based Matched RFID Yoking Making It More Practical and Efficient

    A Radio Frequency IDentification (RFID) yoking proof allows an off-line verifier to make sure whether two tags are simultaneously present. Due to off-line property, a reader cannot differentiate valid from invalid proof records when it probes tags, and would generate lots of useless data. This paper proposes a tree-based matched...
