Cognitive radio network is expected to use flexible radio frequency spectrum sharing techniques to achieve more efficient frequency spectrum usage. This article considers the spectrum sharing problem that one primary user (PU) can share its frequency spectrum by renting this spectrum to multiple secondary users (SUs). The pricing scheme is a key issue for spectrum sharing in cognitive radio network...
In this paper, we study a downlink band allocation game and algorithms in heterogeneous networks consisting of eNodeB (eNB) and femtocells (FC). If eNB and FC act as selfish players which compete to maximize their own utility, the resulting Nash equilibria (NE) may show poor performance due to interference. We propose an algorithm to avoid such equilibria. Specifically, we impose high prices on certain...
Flexible channelization can enhance spectrum efficiency by adapting channel bandwidth and center frequency compared with traditional fixed width channel. The key challenge of this new mechanism lies in how to determine proper channel width for each link in a distributed manner without coordination. In this work, we investigate the spectrum sharing problem with flexible channelization from game-theoretic...
This paper proposes an optimal non-cooperative power allocation game scheme for multi-user multiple-input multiple-output (MU-MIMO) with signal to leakage and noise ratio (SLNR) precoding. The proposed game scheme sets the value of per user SLNR and allocated power as reference for punishment price. Considering the effect of channel correlation and channel estimation error, an alternative robust power...
This paper proposes Forwarding Game Routing Protocol (FGRP), which can be applied to any routing protocol in mobile ad hoc network (MANET) such as Ad Hoc On Demand Distance Vector (AODV) and Dynamic Source Routing (DSR) routing protocols. A node enters the forwarding game upon receiving a flooding packet. In this game, nodes select one of the following mixed strategies: (1) forwarding and (2) not-forwarding...
In this paper, we consider the problem of interference mitigation in the downlink of multicell networks via base station coordination. In this paper, a simple and efficient scheme for interference management based on potential game is proposed. The main emphasis of this paper is placed on the problem of users' quality of service (QoS) in order to maximize the efficient throughput of system. Meanwhile,...
In the wireless Ad-hoc networks, the Relays which transmit message are selfish, they need to consume their energy and compute resources to transmit message. For the problems of the message transmission interrupted by Relay selfishness and the decrease of secrecy rates, we have proposed a Relay-selection method to ensure the security of the Ad-hoc network using game theory incentive mechanism. The...
The tremendous growth of urbanization calls for several interventions for the efficient and environmentally sustainable management of various urban processes, including the road traffic management. Indeed, transportation engineers need to be able to understand how drivers decide their route to effectively address the plethora of challenges for alleviating the congestion phenomena in city areas. In...
Interference mitigation is a major challenge in deploying a two-tier small cell network, where small cells are deployed underlaying a central macrocell and share the same spectrum with the macrocell. In this paper, we develop a new decentralized power control solution for interference mitigation in a two-tier small cell network, from a game theoretic perspective. We aim to maximize the number of small...
Spectrum leasing is a novel promising technique to improve the spectrum efficiency (SE) through the spectrum owner leasing its free or under-utilization spectrum to unlicensed users for superfluous spectrum revenue, while the unlicensed users should pay for spectrum renting. Recently, spectrum leasing is used between femtocell service provider (FSP) and the coexisting macrocell service provider (MSP)...
