  • Multihop Relaying in Millimeter Wave Networks: A Proportionally Fair Cooperative Network Formation Game
    2015
    Co-Authors: Nof Abuzainab, Corinne Touati
    Abstract:

    Millimeter wave channels suffer from considerable degradation in the channel quality when the signal is Non Line of Sight (NLOS) between the source and the destination. Multihop relaying is thus anticipated to improve the communi- cation between a source and its destination. This is achieved by transmitting the signal to a sequence of relays in which a Line of Sight (LOS) signal exists between two nodes along the path, or more generally when the signal is better than the transmitted signal directly from the source to the destination. In this paper, we consider a millimeter wave Network composed of multiple source- destination pairs and a set of deployed relays. We formulate the problem of multihop relaying as a Cooperative Network formation game in which each relay chooses which source-destination pair to assist in order to improve the end-to-end performance, that is, the multihop delay between the source and the destination. Further, we present an algorithm based on the Nash Bargaining Solution to ensure fairness among the different source-destination pairs and assess its efficiency on numerical simulations.

  • Exact Symbol Error Probability of Hybrid/Integrated Satellite-Terrestrial Cooperative Network
    IEEE Transactions on Wireless Communications, 2013
    Co-Authors: Sokchenda Sreng, Benoît Escrig, Marie-laure Boucheret
    Abstract:

    In this paper, we study the Symbol Error Probability (SEP) performance of a hybrid/integrated satellite-terrestrial Cooperative Network. In particular, we focus on the case of mobile relays that forward the satellite signal to a masked mobile destination node. The Selective Decode-and-Forward (SDF) transmission scheme is implemented and only the relay nodes which can successfully decode the satellite message are selected to retransmit the signal. The destination node exploits the spatial diversity advantages by implementing a typical Maximum Ratio Combining (MRC) technique. The closed-form expressions for the exact average SEP of the arbitrary M-ary phase shift keying and M-ary quadrature amplitude modulation signaling with MRC diversity reception over independent but not necessarily identically distributed fading channels are derived using a Moment Generating Function (MGF) approach. These closed-form expressions are represented in terms of a finite sum of Lauricella hypergeometric functions. The analytical expressions show excellent agreement with the simulation results. Numerical results show that for a system using QPSK under the frequent heavy shadowed fading condition, the diversity gain of approximately 7 dB can be obtained at the SEP of 10^{-1} with respect to the direct transmission, when only one relay is used. It increases to around 12 dB in the case of 3 relays.
