    New Encoding Method for Low Power Sequential Access ROMs

    In this paper the authors propose a new ROM data encoding method that takes into account of a sequential access pattern to reduce the power consumption in ROMs used in applications such as FIR filters that access the ROM sequentially. In the proposed encoding method, the number of 1's, of...

    A Robust Trust Management Scheme Against the Malicious Nodes in Distributed P2P Network

    Trust management evaluates the user trust value of participating nodes in the network based on the past behaviors and satisfaction of sharing resources. However, there also exists security issue even though it has been considered to be safe because malicious user is able to affect the trust management with negative...

    Interference Cancellation Using Logic or Operation in MIMO Receiver

    Lately, interference cancellation is a hard challenge in a cellular communication system. In this paper, the authors consider the interference cancellation using logic OR gate from the Multiple Input Multiple Output (MIMO) interference channel where each transmitter and receiver equipped with single or multiple antennas. In their system, they have...

    An Object Version Transcoding for Streaming Media Services in Wireless Networks

    Transcoding has a significant effect on streaming media services in wire-less networks. The goal of this paper is to reduce network traffic due to high network bandwidth demand and streaming constraints, and enhance the performance of streaming media services. Therefore, the authors propose a new OVT (Object Version Transcoding) mechanism...

    A Proxy Caching Scheme Based on Partition and Mapping of Media Block Segments

    Many studies have been performed for streaming of multimedia data in response to the recent increase in requests for wireless services and multimedia services based on distributed networks. The typical schemes for distributed multi-media service are CMD (Centralized Multimedia Distribution), client-server architecture, CDN (Content Distribution Network) and P2P- (Peer-To-Peer) based...

    TRM-Based Multimedia Streaming Optimization Scheme in Wireless Networks

    In this paper, the authors propose a TRM (Transmission Rate Monitoring) based streaming optimization scheme to minimize packet loss and improve QoS (Quality of Service) in wireless networks. The proposed scheme is based on the trade-off relationship between transmission rate monitoring and overhead monitoring. For this purpose, they propose a...

    A Study on Recent Approaches in Handling DDoS Attacks

    In this paper, the authors present a study on the recent approaches in handling Distributed Denial of Service (DDoS) attacks. DDoS attack is a fairly new type of attack to cripple the availability of Internet services and resources. A DDos attack can originate from anywhere in the network and typically...

    Iteratively Suboptimum Decoder Design for Distributed Space-Time Coding Based on Distributed Interleavers

    The authors have presented a detailed analysis on the problem of distributed space-time coding employing Amplify-and-Forward (AF) protocol for synchronized wireless relay networks, where Maximum Likelihood (ML) decoding is employed. In this paper, an iterative turbo-like decoder is introduced to improve system performance by allocating interleavers at each relay node...
