    Using a Multi-Agent System for Network Management

    In this paper, the authors present a system for dynamic network resource configuration in environments with bandwidth reservation and path restoration mechanisms. The objective is to avoid conflicts between the mechanisms that make changes over the same resources (i.e. bandwidth, restoration, and spare capacity planning) enabling its integration. The system...

    Energy Reduction for Centralized Cognitive Radio Networks With Distributed Cognitive Pilot Channels

    In this paper, a method for energy reduction in a centralized Cognitive Radio Network (CRN) is presented. The basic model of the CRN provides signaling through Cognitive Pilot Channels (CPCs) distributed in every available channel or frequency slot. The control is performed by using frequency-division and time-division multiplexing techniques. This...

    Designing Context-Aware Adaptive Units of Learning Based on IMS-LD Standard

    Learning contents adaptation has been a subject of interest in the research area of the adaptive hypermedia systems. Defining which variables and which standards can be considered to model adaptive content delivery processes is one of the main challenges in pedagogical design over e-learning environments. In this paper some specifications,...

    Context-Aware Adaptation Process to Build Units of Learning Based on Ims-Ld Standard

    Mobile and ubiquitous computing are changing the way how the students are learning. Heterogeneity of learner preferences in learning processes using Learning Management Systems (LMS) is a problem that researchers have been focused in the last few years. With the existence of different devices to access, technologies to interact, learning...

    A Quality-Based Cost Distribution Charging Scheme for QoS Multicast Networks

    This paper presents a new charging scheme for cost distribution along a point-to-multipoint connection when destination nodes are responsible for the cost. The scheme focus on QoS considerations and a complete range of choices is presented. These choices go from a safe scheme for the network operator to a fair...

    Integrated User Model in an Adaptive Virtual Learning Environment

    This paper presents an integrated user model which supports the development of an adaptive virtual learning environment. This integrated user model is made up of three dimensions user characteristics, interactions and context which allow one to address three issues in adaptive systems. User characteristics are used to support adaptive paper,...

    Adaption of Courses and Learning Environment to the User Context in DotLRN

    The explosive growth of Internet during the last years has been reflected in the ever-increasing amount of the diversity and heterogeneity of user preferences, types and features of devices and access networks. Usually the heterogeneity in the context of the users which request web contents is not taken into account...

    Dynamic AUV Mission and Data Visualization With Google Earth

    AUVs are currently being used for doing scientific observations of deep ocean water where it is difficult for humans to reach. As these vehicles are autonomous and moving underwater, it is difficult for operators and Engineers know what they are doing. This report describes an implementation of a dynamic AUV...
