  • A DISTANCE-AWARE SAFETY-RELATED MESSAGE BROADCASTING ALGORITHM FOR VEHICULAR NETWORKS
    Xiaohuan Li, Bin-jie Hu, Hongbin Chen, Jin Ye    Download Full Text

    A new distance-aware broadcasting algorithm was proposed to enhance the propagation distance in the latency time of safetyrelated message broadcasting. The IEEE 802.11p standard states that if the medium is detected as idle, a station would defer its transmission within a backoff time to avoid collisions with other stations.The backoff times follow uniform distribution over [0, CW]. In this way, f...

  • A MODEL FOR VIDEO QUALITY ASSESSMENT CONSIDERING PACKET LOSS FOR BROADCAST DIGITAL TELEVISION CODED IN H.264
    Jose Joskowicz, Rafael Sotelo    Download Full Text

    This paper presents a model to predict video quality perceived by the broadcast digital television (DTV) viewer. We present how noise on DTV can introduce individual transport stream (TS) packet losses at the receiver. The type of these errors is different than the produced on IP networks. Different scenarios of TS packet loss are analyzed, including uniform and burst distributions. The results sh...

  • BROADCASTING WITH PREDICTION AND SELECTIVE FORWARDING IN VEHICULAR NETWORKS
    Jianjun Yang, Zongming Fei    Download Full Text

    Broadcasting in vehicular networks has attracted great interest in research community and industry. Broadcasting on disseminating information to individual vehicle beyond the transmission range is based on inter-vehicle communication systems. It is crucial to broadcast messages to other vehicles as fast as possible because the messages in vehicle communication systems are often emergency messages ...

  • BROADCASTING ALGORITHMS OF THREE-DIMENSIONAL PETERSEN-TORUS NETWORK
    Jong-Seok Kim, Hyeong-Ok Lee, Mihye Kim, Sung Won Kim    Download Full Text

    The three-dimensional Petersen-torus network 3PT is based on the Petersen graph and has recently been proposed as an interconnection network. 3PT is better than the well-known 3D torus and 3D honeycomb mesh in terms of diameter and network cost. In this paper, we propose one-to-all and all-to-all broadcasting algorithms for 3PT(l; m; n) under SLA (single-link available) and MLA (multiple-link avai...

  • INTERFERENCE COORDINATION FOR E-MBMS TRANSMISSIONS IN LTE-ADVANCED
    Alberto A Lopes, Jose Seguro, Paulo Gomes, Nuno Souto, Americo Correia    Download Full Text

    Interference coordination methods for Evolved-Multimedia Broadcast/Multicast Service (E-MBMS) in Long-Term Evolution Advanced (LTE-A) are presented. In addition, we consider signal space diversity based on Rotation Matrices (RM) known to provide good performance gains over uncorrelated Rayleigh fading channels. OFDM/OFDMA systems can make the use of RM very attractive both for single andmultipl...

  • PERFORMANCE AND IMPLEMENTATION EVALUATION OF TR PAPR REDUCTION METHODS FOR DVB-T2
    Mohamad Mroue, Amor Nafkha, Jacques Palicot, Benjamin Gavalda, Nelly Dagorne    Download Full Text

    High Peak to Average Power Ratio (PAPR) is a critical issue in multicarrier communication systems using Orthogonal Frequency Division Multiplexing (OFDM), as in the Second Generation Terrestrial Digital Video Broadcasting (DVB-T2) system. This problem can result in large performance degradation due to the nonlinearity of the High Power Amplifier (HPA) or in its low power efficiency. In this pap...
