This paper considers the multiuser power control problem in a frequency-selective interference channel. The interference channel is modeled as a noncooperative game, and the existence and uniqueness of a Nash equilibrium are established for a two-player version of the game. An iterative water-filling algorithm is proposed to efficiently reach the Nash equilibrium. The iterative water-filling al...
Voronoi game presents a simple geometric model for Competitive facility location problems with two players. Voronoi game is played by two players known as White and Black, they play in a continuous arena. In the one-round game, White starts game and places all his points in the arena then Black places her points. Then the arena is divided by distance between two players and the player with the ...
SUMMARY It has been shown that power control is an efficient approach to achieve the quality of service (QoS) requirement in wireless networks. In this letter, we present a utility function that denotes the QoS and energy efficiency of each wireless terminal. We propose a framework of power control based on the game theory for the QoS of wireless mesh networks (WMNs). In this framework, all pla...
In wireless communication systems, each user’s signal contributes to the interference seen by the other users. Given limited available battery power, this creates a need for effective and efficient power control strategies. These strategies may be designed to achieve quality of service (QoS) or system capacity objectives, or both. We show how the power control problem is naturally suited to for...
The paper technically proposes a newly secure scheme for simultaneous wireless power and information transfer (SWIPT) frameworks. We take into account an orthogonal frequency division multiplexing (OFDM)-based game which is in relation to a multi-input multi-output multi-antenna Eavesdropper (MIMOME) strategy. The transceiver is generally able to witness the case imperfect channel state informa...
In this paper, we investigate a joint uplink pilot and data power allocation strategy for energy-efficient communications under pilot contamination in multi-cell multi-user massive multiple-input multiple-output (MU-Massive-MIMO) systems. Assuming the maximum-ratio combining detection and a large number of antennas at the base station, the system energy efficiency (EE) is maximized over the ind...
Game theory is a set of tools developed to model interactions between agents with conflicting interests, and is thus well-suited to address some problems in communications systems. In this paper we present some of the basic concepts of game theory and show why it is an appropriate tool for analyzing some communication problems and providing insights into how communication systems should be desi...
Introduction: This research investigated the effects of violent and football video games on cognitive functions, cortisol levels, and brain waves. Methods: A total of 64 participants competed in a single-elimination tournament. Saliva samples of all players were obtained before and after the games for the assessment of cortisol levels. The cognitive performances of the players were also assess...
Power flow control and transmission loss minimization model with TCSC for practical power networks " , in proc. Purnomo, " Fuzzy clustering based on multiobjective optimization problem for decision support of non player character in serious game " ,
cooperation is the foundation of many protocols in wireless networks. without cooperation, the performance of a network significantly decreases. hence, all nodes in traditional networks are required to cooperate with each other. in this paper, instead of traditional networks, a network of rational and autonomous nodes is considered, which means that each node itself can decide whether to cooper...
