Energy-efficient design of two-tier femtocell networks
With the exponential increase in mobile internet traffic, future cellular networks face great challenges to satisfy the demand of network capacity. At the same time, high data rate transmission and rapid increasing number of users also seriously burden the power consumption and the cost of cellular networks. Base station (BS) is the main part of power consumption, so reducing energy consumption...
متن کاملEnergy-efficient downlink resource management in self-organized OFDMA-based two-tier femtocell networks
Femtocell is a novel technology that is used for escalating indoor coverage as well as the capacity of traditional cellular networks. However, interference is the limiting factor for performance improvement due to co-channel deployment between macrocells and femtocells. The traditional network planning is not feasible because of the random deployment of femtocells. Therefore, self-organization ...
متن کاملDecentralized spectrum sharing with beamforming in two-tier femtocell networks
Two-tier overlay networks that consist of a conventional macrocell network and femtocell hotspots offer an economical solution for high capacity and extended coverage. However, wireless interference across tiers significantly degrades network performance by restricting spectrum reuse. In this paper, we explore schemes to mitigate cross-tier interference using beamforming in overlay networks. In...
متن کاملImproving Energy Efficiency of Two-tier OFDMA Femtocell Networks with Distributed Power Control
This paper addresses how to improve the energy efficiency of two-tier OFDMA femtocell networks using power control. Firstly, the energy efficiencies of two typical power control methods are analyzed, including fixed power setting (FPS) and minimum power consumption (MPC) methods. Then a distributed maximum energy efficiency (MEE) method is proposed. Each macrocell and femtocell dynamically adju...
متن کاملLow Complex Energy-Efficient Resource Allocation in Femtocell Networks
Femtocells have attracted growing attention in academia, industry, and standardization forums in recent years. However, most of existing works on femtocell networks are focused on spectrum efficiency and interference mitigation, energy efficiency aspect is neglected. In this paper, we investigate the energy efficient resource allocation of downlink femtocell networks in sparsely and densely dep...
