    A Privacy-Preserving Cloud Computing System for Creating Participatory Noise Maps

    Participatory sensing is a crowd-sourcing technique which relies both on active contribution of citizens and on their location and mobility patterns. As such, it is particularly vulnerable to privacy concerns, which may seriously hamper the large-scale adoption of participatory sensing applications. In this paper, the authors present a privacy-preserving system...

    Performance Evaluation of TCP in IEEE 802.16 Networks

    An important application for the IEEE 802.16 technology (also called WiMAX) it to provide high-speed access to the Internet where the Transmission Control Protocol (TCP) is the core transport protocol. In this paper, the authors study through extensive simulation scenarios, the performance characteristics of five representative TCP schemes, namely TCP...

    A Software-Supported Methodology for Designing General-Purpose Interconnection Networks for Reconfigurable Architectures

    Modern applications realized onto FPGAs exhibit high connectivity demands. Throughout this paper, the authors study the routing constraints of Virtex devices and they propose a systematic methodology for designing a novel general-purpose interconnection network targeting to reconfigurable architectures. This network consists of multiple segment wires and SB patterns, appropriately selected...

    Comparative Performance Evaluation of Routing Algorithms in IEEE 802.11 Ad Hoc Networks

    In this paper the authors examine the behavior of Ad Hoc networks through simulations, using different routing protocols and various topologies. They examine the difference in performance, using CBR application, with packets of different size through a variety of topologies, showing the impact node placement has on networks performance. They...
