    Wavelet Packet Transform Modulation for Multiple Input Multiple Output Applications

    An investigation into the Wavelet Packet Transform (WPT) modulation scheme for Multiple Input Multiple Output (MIMO) band-limited systems is presented. The implementation involves using the WPT as the base multiplexing technology at baseband, instead of the traditional Fast Fourier Transform (FFT) common in Orthogonal Frequency Division Multiplexing (OFDM) systems. An...

    Full Data Controlled Web-Based Feed Aggregator

    Feed syndication is analogous to electronic newsletters, both are aimed at delivering feeds to subscribers; the difference is that while newsletter subscription requires e-mail and exposed you to spam and security challenges, feed syndication ensures that you only get what you requested for. This paper reports a review on the...

    Learning Performance and Adaptive Hypermedia Learning Systems: Prior Knowledge Vs. Cognitive Styles

    In the past decade, a number of adaptive hypermedia learning systems have been developed. However, most of the systems tailored presentation content and navigational support basing on prior knowledge or cognitive styles of students separately. There is a need to, however, explore how the two individual difference characteristics could be...

    ERP Implementation: An Integrative Methodology

    Many companies are radically changing their information technology strategies to maintain a competitive advantage, become more responsive to change markets, and deliver better service at lower cost by purchasing off-the-shelf integrated ERP software instead of developing IT systems in-house. Though ERP systems are being widely implemented in many organizations, there...

    Analytical Modelling of the GC-Based Handover Scheme with Heavy-Tailed Call Holding Times

    The Guard Channel (GC) scheme is an extensively deployed handover prioritization policy in wireless mobile networks due to its appealing properties of easy implementation and flexible control. Self-similar traffic has been demonstrated to be a ubiquitous phenomenon in modern communication networks and many measurement studies have demonstrated that the call...

    Performance Modelling and Analysis of Interconnection Networks with Spatio-Temporal Bursty Traffic

    The k-ary n-cube which has an n-dimensional grid structure with k nodes in each dimension has been a popular topology for interconnection networks. Analytical models for kary n-cubes have been widely reported under the assumptions that the message destinations are uniformly distributed over all network nodes and the message arrivals...

    Email Threads: A Comparative Evaluation of Textual, Graphical and Multimodal Approaches

    Email threads were implemented by enormous number of studies in order to improve the efficiency of email clients. Nevertheless, contextual information about messages in the threads was somewhat neglected by most of these studies. This paper describes an empirical study carried out to investigate into how extent can such information...

    Implementation of a Knowledge Management Tool Within a VDO Network: Preliminary Results

    This paper presents a Knowledge Management (KM) software tool which has been designed to support managing implementation of best practices and improvement initiatives within a VDO (Virtual Development Office) Network. A VDO Network is an organization integrated by SMEs, with a particular form of governance. Furthermore, the KM tool enables...

    An Application Layer Architecture for Seamless Roaming

    The paper advances a new architecture for seamless roaming, which is implemented at the application layer. This architecture is subject for the research projects PERIMETER and MOBICOME, recently granted by the EU STREP FP7 and EUREKA, respectively. The research challenges are on mobility management, security, QoE management, overlay routing, node...

    Improving Route Discovery of Dynamic Probabilistic Flooding in On-Demand Routing Protocols for MANETs

    In Mobile Ad hoc NETworks (MANET), broadcasting is widely used in route discovery and many other network services. The efficiency of broadcasting protocol can affect the performance of the entire network. As such, the simple flooding algorithm aggravates a high number of unnecessary packet rebroadcasts, causing contention and packet collisions....

    Dynamic Path Substitution Localized QoS Routing Scheme

    Localized Quality of Service (QoS) routing schemes make routing decisions based on locally collected network state. But most QoS schemes proposed use global network state that requires periodic exchanges of network state among the routers. This results in communication overheads and processing overhead. The Localized (QoS) routing schemes avoid these...

    New Performance Analysis of Angle Routing AODV Protocol in MANETs

    The ultimate goal of the MANET community is to provide a set of standardized protocols that can be both robust and scalable. This paper proposes routing protocol based on the best heading direction angle route. The protocol is designed to calculate the average of all heading direction angles in the...
