Developed Mechanisms for CROSS-TIER and CO-TIER Interference Avoidance in FEMTOCELL NETWORKS
To deal with the increasing demand of high speed data streaming and good quality voice traffic from mobile users at home, Femtocell Networks are deployed in homes that enables an indoor mobile user to achieve high speed downloading from the internet and make good quality voice calls. A femtocell network also provides relief to an overloaded macrocell network by servicing mobile users at home wh...
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 کاملA Game Theory Approach for Efficient Power Control and Interference Management in Two-tier Femtocell Networks based on Local Aain
In the recent years, femtocell technology has received a considerable attention due to the ability to provide an efficient indoor wireless coverage as well as enhanced capacity. However, under the spectrum sharing between femtocell user equipment (FUEs) and the owner of spectrum macrocell user equipment (MUEs), both may experience higher uplink interference to each other. This paper proposes a ...
متن کاملCognitive Interference Management for Autonomic Femtocell Networks
The femtocell concept is an emerging technology for deploying the next generation of the wireless networks, aiming at indoor coverage enhancement, increasing capacity, and offloading the overlay macrocell traffic. Nevertheless, one of the most critical issues in femtocells deployment is the potential interference, thus mitigating the overall system capacity. Inspired by the cognitive radio tech...
متن کاملEnergy-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...
