    Anonymous Traceback of Network Data Packets

    Since its early days, the Internet has witnessed not only a phenomenal growth, but also various security attacks, some even designed to cause large-scale service disruptions often for extended periods of time. In recent years, Distributed Denial-of-Service (DDoS) attacks have emerged as one of the top threats to the Internet...

    Subcarrier, Bit and Time Slot Allocation for Multicast Precoded OFDM Systems

    The conventional resource allocation method in multicast OFDM systems adapts the physical layer to the worst user link conditions. In this paper, the authors propose new sub-carrier, bit and time slot allocation algorithms for multicast OFDM systems in indoor Power-Line Communication (PLC) context. To increase the multicast bit rate, these...

    Bit Rate Maximization for Multicast LP-OFDM Systems in PLC Context

    In this paper, the authors propose a new resource allocation algorithm based on linear precoding technique for multicast OFDM systems. Linear precoding technique applied to OFDM systems has already proved its ability to significantly increase the system throughput in a PowerLine Communication (PLC) context. Simulations through PLC channels show that...

    Coding Improves the Throughput-Delay Trade-Off in Mobile Wireless Networks

    In large-scale wireless networks, a fundamental question is how much information one source node can transmit to a destination in the presence of other simultaneous transmissions when the number of nodes grows large. In their seminal paper, Gupta and Kumar investigate the network layer throughput, or the capacity, of large-scale...

    Cooperative Routing for Wireless Networks Using Mutual-Information Accumulation

    Cooperation between the nodes of wireless multihop networks can increase communication reliability, reduce energy consumption, and decrease latency. The possible improvements are even greater when nodes perform mutual information accumulation using rateless codes. In this paper, the authors investigate routing problems in such networks. Given a network, a source, and...

    Cross-Layer Resource Allocation Scheme for Multi-Band High Rate UWB Systems

    In this paper, the authors investigate the use of a cross-layer allocation mechanism for the high-rate Ultra-WideBand (UWB) systems. The aim of this paper is twofold. First, through the cross-layer approach that provides a new service differentiation approach to the fully distributed UWB systems, they support traffic with Quality of...
