...owers in order to maximize their utilities, where utility is defined as the ratio of throughput to transmit power. A game-theoretic approach to joint power control and receiver design is presented in =-=[13]-=-, and power control for multicarrier systems is studied in [14]. The authors in [8] use pricing to obtain a more efficient solution for the power control game. Similar approaches are taken in [9]–[12]...

...joule of energy consumed. The analysis is extended in [19] by introducing pricing to improve the efficiency of Nash equilibrium. Joint energy-efficient power control and receiver design is studied in =-=[22]-=-. In addition, a gametheoretic approach to energy-efficient power allocation in multicarrier systems is presented in [23]. Joint network-centric and user-centric power control is discussed in [16]. In...

The information theoretic results derived in [28], [29] focus only on transmit power when considering energy consumption during transmission. Typically a device will incur additional circuit power d...

...me approaches are constructed to enforce cooperation and to study better cooperation. Some recent works for game theory to enhance energy-efficient behavior in infrastructure networks can be found in =-=[12]-=-–[15]. However, for packet-forwarding networks, there exists the so-called curse of boundary nodes. The nodes at the boundary of the network must depend on the backbone nodes in the middle of the netw...

...ys should depend on its transmit power, since this determines the interference it is creating to the rest of the network. There are various ways of integrating a power-related cost in the utility. In =-=[38]-=- for instance, the utility is the ratio of the goodput by the power level itself. Additive costs are also possible, in which case, denoting the cost paid by each user by cn(pn), we can rewrite the non...

Recently, [20] has shown that this assumption is also justified from an information-theoretic standpoint. At a given instant, the SINR at receiver i ∈ K writes as: SINRi = pi|gi| 2 ∑ j̸=i pj|gj| 2 +...

For example, the lowest order modulation should be always used while accommodating the delay constraint [8] to minimize energy consumption. The information-theoretic results derived in [7], [8] focu...

.... Numerous works on power allocation games have followed since, a selection of which we present in Sec. II. In particular, this contribution can be considered as an extension of previous work such as =-=[12]-=-, as detailed in Sec. II. Game theory can be used to treat the case of any number of players. However, as the size of the system increases, the number of parameters increases drastically and it is dif...

While the above papers consider the issue of power control assuming that a conventional matched filter is available at the receiver, the recent paper =-=[10]-=- considers the cross-layer problem of joint linear receiver design and power control so as to maximize the utility of each user: it is thus shown in [10] that the inclusion of receiver design in the c...
