In this article, we investigate energy efficient power control for the uplink of an OFDMA single-cell communication system. The user equipments decide freely their power level on the available subcarriers of the system in order to maximize their EE (Energy Efficiency) while respecting minimum normalized rate requirements. We use the non-cooperative Game theory to demonstrate that users will end by...
In task allocation problems one usually only considers a single round in which players participate. In practice, many allocation problems are of repeated nature, in which players can decide to keep participating or leave. Players' participation, or behavior, influences the outcome, or social welfare, of these problems. In this paper, we use a fuzzy connective to model agents' behavior in regard to...
In this paper, we investigate the selling strategy and price decisions for a seller who provides two complementary products to the strategic consumer over two periods under three selling strategies: markdown pricing (MD), second period bundling (SPB) and first period bundling (FPB). It is found that the seller's optimal prices in the second period of SPB and FPB strategies are higher than that of...
The study of the carbon obligation allocation among different members in the power system holds significant theoretical and practical value. Existing methods for carbon emission estimation usually attribute the emission responsibility to single side (either generation side or demand side). However, both the generation side and the demand side should take the responsibility of carbon reduction and...
This paper mainly focuses on developing a joint cloud and wireless resource allocation algorithm based on evolutionary game (JRA-EG) considering mobile terminals' energy consumption and time delay as well as monetary cost in mobile edge computing environment. The mobile terminals (MTs) in different service areas form different populations. In addition, the competition among populations of MTs in different...
As the complexity and number of cybersecurity incidents are growing, the traditional security measures are not sufficient to defend against attackers. In this situation, cyber threat intelligence capability substantially improves the detection and prevention of the sophisticated attacks. Cybersecurity information sharing is a key factor of threat intelligence, allowing organizations to detect and...
For task completion in distributed environments, a set of resources is required and a group of agents must cooperate in deciding the share each should provide to maximize the system performance. We address the problem from an evolutionary game-theoretic perspective and present a fully distributed algorithm based on local replicator dynamics. By using the optimality condition, we prove the convergence...
We investigate a formal characterisation of interactional justice asa mechanism for self-organisation of institutional rules in an open system, in order to address issues of congruence, acceptability and risk. The process of interactional justice uses opinion formation over a social network with respect to a shared set of congruent values, to transform a set of individual, subjective self-assessments...
In this paper we use grammar-directed procedural content generation (PCG) techniques to develop folklore; based on the seven basic story plots, for a simulated religion. A hierarchy of values for a simulated community was first generated. Using these values, a variety of deities were procedurally generated, each with their own reflected values and persona. A Context-Free Grammar is then traversed...
Small cells are low-powered cellular radio access nodes which make best use of available spectrum by reusing the same frequencies many times within a geographical area. However, the deployment of small cells (e.g., femtocells) may introduce extra interferences such as cross-tier(macrocellfemtocell) and co-tier (femtocell-femtocell) interferences. In this regard, an effective interference management...
This paper investigates the problem of power allocation for radar network in a cooperative game-theoretic framework such that the low probability of intercept (LPI) performance can be improved. Taking into consideration both the transmit power constraint and the minimum signal-to-interference-plus-noise ratio (SINR) requirement of each radar, a cooperative Nash bargaining power allocation game (NBPAG)...
Public-private partnership (PPP) model has become an important solution of governments to provide infrastructures. In the execution of the PPP projects contracts, however, inevitably to renegotiate, which might affect the execution efficiency of PPP contracts. This paper built two PPP projects renegotiation bargaining game models of the private sectors and public sectors respectively through the analysis...
This paper investigates distributed resource allocation in next-generation underlay Device-to-Device (D2D) networks. The joint channel and power allocation for a D2D network underlaying a cellular network is formulated as a non-cooperative game. A utility-based learning algorithm which does not require information exchange between device pairs is proposed to determine the channel index and power level...
One significant challenge in cognitive radio networks is to design a framework in which the selfish secondary users are obliged to interact with each other truthfully. Moreover, due to the vulnerability of these networks against jamming attacks, designing anti-jamming defense mechanisms is equally important. In this paper, we propose a truthful mechanism, robust against the jamming, for a dynamic...
Many classification techniques can automatically summarize text into topics and accordingly identify topic terms from the online reviews. Among these techniques Latent Dirichlet Allocation (LDA) and Latent Semantic Analysis (LSA) are some of the most often employed approaches. LDA is a probability generated model that projects a document into the topic space using Dirichlet Distribution, and each...
Cognitive radio is a promising technology to relieve the pressure of spectrum crisis with the sharp increasement of wireless services. In this paper, the game model for spectrum leasing in cognitive radio network is considered, where the Primary Transmitter(PT) will choose some Secondary Transmitter(ST) as relay to resist multi-path fading and enhance the transmission efficiency. As a reward, the...
Cloud Radio Access Network (C-RAN) is a promising technology to improve user quality of service and reduce network capital and operating costs. The key concept behind C-RAN is to break down the conventional base station into a Base Band Unit (BBU) and a Remote Radio Head (RRH), and to pool BBUs from multiple sites into a single geographical point. Moreover, to achieve statistical multiplexing gain,...
In this paper, the problem of joint users' uplink transmission power and rate allocation in NOMA wireless networks is studied, under the scenario that each user is simultaneously requesting multiple services. Each user is associated with a two-variable utility function that represents his satisfaction from his allocated resources (i.e., power and rate). In order to appropriately reflect the combined...
We investigates a two-echelon supply chain with one risk-natural supplier and one loss-averse retailer where there is one short life cycles product with stochastic demand. The loss-averse preference is adopted to describe the retailer's decision-making behavior. We introduce a combined contract by organically combining the quantity flexibility contract and the buy-back contract with this issue. It...
More and more real-time IoT applications such as smart cities or autonomous vehicles require big data analytics with reduced latencies. However, data streams produced from distributed sensing devices may not suffice to be processed traditionally in the remote cloud due to: (i) longer Wide Area Network (WAN) latencies and (ii) limited resources held by a single Cloud. To solve this problem, a novel...
