With the introduction of femtocells, cellular networks are moving from the conventional
centralized network architecture to a distributed one, where each network cell should make …

Interference control and quality-of-service (QoS) awareness are the major challenges for
resource management in orthogonal frequency-division multiple access femtocell networks …

Femtocell networks, consisting of a conventional macro cellular deployment and overlaying
femtocells, forming a hierarchical cell structure, constitute an attractive solution to improving …

In order to improve the spectrum efficiency in the femtocell network and mitigate the co-
tier/cross-tier interference, we propose a novel graph-theoretic scheme based on coloring …

One of the effective techniques of improving the coverage and enhancing the capacity and
data rate in cellular wireless networks is to reduce the cell size (ie, cell splitting) and …

We consider the joint resource allocation and admission control problem for Orthogonal
Frequency-Division Multiple Access (OFDMA)-based femtocell networks. We assume that …

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 …

Small cells such as femtocells overlaying the macrocells can enhance the coverage and
capacity of cellular wireless networks and increase the spectrum efficiency by reusing the …

Femtocells have been considered as a promising technology to provide better indoor
coverage and spatial reuse gains. However, the co-channel deployment of macrocells and …

The demand for increased spectral efficiencies is driving the next generation broadband
access networks towards deploying smaller cells (femtocells) with sophisticated air interface …
