    Abstract

    Transmitters of a multiple access channel are assumed to freely choose their
    power control strategy in order to be energy-efficient. We show that in a
    stochastic game framework, we can develop energy-efficient distributed control
    strategies which only require partial knowledge of the entire system.
    Achievable utility equilibrium region is characterized and based on
    time-sharing, an explicit power control strategy is proposed.

    Abstract

    We analyze the problem of distributed power allocation for orthogonal
    multiple access channels by considering a non-cooperative game whose strategy
    space corresponds to the users' distribution of transmission power over the
    network's channels. When the channels are static, we find that this game admits
    an exact potential function and this allows us to show that it has a unique
    equilibrium almost surely.

    Abstract

    This paper is concerned with the concept of equilibrium and quality of
    service (QoS) provisioning in self-configuring wireless networks with
    non-cooperative radio devices (RD). In contrast with the Nash equilibrium (NE),
    where RDs are interested in selfishly maximizing its QoS, we present a concept
    of equilibrium, named satisfaction equilibrium (SE), where RDs are interested
    only in guaranteing a minimum QoS. We provide the conditions for the existence
    and the uniqueness of the SE.

  4. A Repeated Game Formulation of Energy-Efficient Decentralized Power Control.

    Abstract

    Decentralized multiple access channels where each transmitter wants to
    selfishly maximize his transmission energy-efficiency are considered.
    Transmitters are assumed to choose freely their power control policy and
    interact (through multiuser interference) several times. It is shown that the
    corresponding conflict of interest can have a predictable outcome, namely a
    finitely or discounted repeated game equilibrium.
