We develop the noncooperative game with individual pricing for the general multiple access channel (MAC) system without successive interference cancellation (SIC). Each user allocates its own power by optimizing the individual utility function with clever price adaptation. We show that by the proposed prices, the best response (BR) power allocation of each user converges rapidly. The individual prices...
In this paper, we study the problems of power allocation in a multi-user relay-assisted wireless network. From the perspective of game theory, we formulate and analyze this power allocation problem as a power trading game by considering users as bidders and the relay as an auctioneer. Aiming at solving this problem where each bidder has a private budget limit, we apply an adaptive clinching auction...
Two non-cooperating cells are considered, each with its protected band to provide service to its high priority users. A shared band for the two cells is employed to deliver service to low priority users. We formulate the situation between the two cells as a non-cooperative game and study its Nash equilibrium. We prove that the game belongs to a class of games called supermodular games which have several...
The issue of non-cooperative, energy-efficient power control in a relay-assisted interference channel is tackled in this paper, based on a game-theoretic approach. A pricing-based utility function is considered, in which the price controls the trade-off between maximizing the achievable rate and saving as much battery power as possible. Unlike most previous related literature, not only the transmit...
In this paper, the issue of non-cooperative, green resource allocation in a multicarrier relay-assisted interference channel is considered. The energy efficiency of a given terminal is defined as the ratio between the throughput of that terminal and the consumed power. Unlike many previous contributions, as far as the computation of the consumed power is concerned, not only the transmit power, but...
In this work the problem of non-cooperative resource optimization in the uplink of a relay-assisted MIMO MAC system with partial CSI at the transmitter is addressed. Each multiple access user pursues individual rate maximization, whereas the relay designs its amplify-and-forward matrix in order to optimize the system's sum-rate. From a game-theoretic perspective, the resource allocation process is...
The problem of non-cooperative resource allocation in an amplify-and-forward relay-assisted DS/CDMA system is addressed. The relay designs its amplify-and-forward matrix for achievable sum-rate maximization, whereas the multiple access users pursue individual achievable rate maximization. The interaction between the relay and the multiple access users has been modeled as a Stackelberg game, with the...
Non-cooperative power control strategies for the uplink of relay-assisted DS/CDMA wireless networks are considered in this paper using game-theoretic tools. Assuming that each user is interested in maximizing his own energy efficiency, measured in bit/Joule and denoting the number of error-free delivered bits for each energy-unit used for transmission, several non-cooperative games are proposed and...
