Game Theoretic Spectrum Allocation in Femtocell Networks for Smart Electric Distribution Grids

Abstract

Ever growing penetration of the behind-the-meter technologies is changing the electricity consumption profiles of end-users. Intelligent coordination of these emerging technologies through a robust communication infrastructure enables their seamless integration with electric utilities' operation. In this context, an efficient and reliable communication infrastructure plays a pivotal role in enabling optimal integration of emerging resources. In this paper, we propose a game-theory based method to enhance efficiency of the underlying communication network. Specifically, we focus on Femtocell communication technology which is one the promising options for improving poor indoor communication coverage. The major drawback for using femtocell communication technology is cross-layer interference of femto users (FUs) and macro users (MUs) which adversely impact network performance. In this paper, we propose a novel approach for sharing spectrum in a cognitive radio system with FUs and MUs as primary and secondary users, respectively. The underlying problem is formulated as Stackelberg game that is joined with a convex optimization problem. In this study, MUs and FUs are assumed to be selfish, rational and motivated to achieve maximum utility function, while MUs are competing to obtain maximum bandwidth. Finally, we present a closed form solution for the proposed approach which obtains a unique Nash Equilibrium and prioritizes the access of MUs to femto-base stations. Simulation results provide proof of concept and verify the effectiveness of our mathematical modeling.

Energy Retrofitting Strategies and Economic Assessments: The Case Study of a Residential Complex Using Utility Bills

“…Finally, a further starting point for reflection on possible developments can be represented by the combined study of retrofitting actions on the thermal envelope associated with the implementation of renewable energies, such as photovoltaic panels. On this topic, interconnection with the electricity grid [30,31] will also come into play.…”

A Fully Distributed Approach for Economic Dispatch Problem of Smart Grid

“…As an alternative to traditional power grid, SG can relieve the burden caused by various energy demands. However, the increasing electricity demand, together with the complex and nonlinear nature of the electric power distribution network, have caused many challenges for the future grid, for example, serious network communication issues [11,12], and it is expensive and unreliable to solve economic dispatch problem (EDP) using traditional centralized methods. SG, with distributed energy sources accessing, require distributed approaches to deal with its energy management problems.…”

Resource Allocation in OFDMA Femtocell Based LTE and 5G Networks with QoS Guarantees

“…Femtocell communication is a cost-effective technology that requires low power, operates in a licensed spectrum and connects to the cellular network via. broadband backhaul connection such as optical fiber or Digital Subscriber Line (DSL) (Mohammadi et al, 2018;Vaezpour et al, 2017). Both of users and operators profit from femtocells.…”

“…Moreover, it can reduce cross-tier interference and improve FAP user's performance reliability. Hence, this access mechanism, adopted in this study, enhances network capacity (Mohammadi et al, 2018;Hatoum et al, 2013;Lopez-Perez et al, 2009).…”

“…Game theoretical resource allocation approaches in femtocell networks are proposed by Pourkabirian et al (2018), Mohammadi et al (2018). Researchers by Pourkabirian et al (2018) proposed a game-theoretic approach for two-tier femtocell networks that takes into consideration macro user's activity and user's QoS requirements in resource allocation.…”
