In this paper, we address the problem of resource allocation under high user density
environment in OFDMA macro-femotcell networks. In the literature, several solutions have …

In this paper, we propose a base station selection and resource allocation model for OFDMA
macro-femtocell networks. Dense deployment of femtocells can cause severe interference …

Femtocell is one of promising key technologies to increase the efficiency and coverage of
next generation broadband wireless networks. However, there exists interference problem …

In this paper, we tackle the problem of resource management in macro-femtocell networks.
Dense deployment of femtocells imposes several challenges for a cluster-based resource …

In this paper, we study power loading and resource allocation for OFDM-based femtocell
networks. To mitigate the interference to the macrocell from the femtocell, interference …

In this paper, we consider the problem of resource allocation in non-dense macrocell–
femtocell networks. We build a comprehensive realistic framework that overcomes the …

In femtocell networks, due to their small cell size, we can achieve higher spatial diversity
from the channel reuse between multiple femtocells. In addition, if femtocells are operated …

OFDMA femtocells in the macrocellular network of which frequency reuse factor is 1 cause
serious interference to macrocell users, while the femtocells improve the performance of …

In this paper, we propose a novel scheme to improve the throughput of femtocell networks.
The proposed scheme consists of two steps: spectrum allocation for femtocells and dealing …

Recently, operators have resorted to femtocell networks in order to enhance indoor
coverage and quality of service since macro-antennas fail to reach these objectives …
