In this paper, we address the problem of optimally placing relay nodes in a cellular network
with the aim of maximizing cell capacity. In order to accurately model interference, we use a …

We investigate the resource-allocation problem in multicell networks targeting the max-min
throughput of all cells. A joint optimization over power control, channel allocation, and user …

We study the network utility maximization problems in wireless networks for service
differentiation that optimize the Signal-to-Interference-plus-Noise Radio (SINR) and …

In a heterogeneous network (HetNet) obtained by overlaying low-power picocells on a
conventional macrocell network, two important problems must be addressed in order to …

The use of unlicensed spectrum for LTE Small Cells is gaining traction amongst cellular
operators. The spectral efficiency of LTE systems in the unlicensed spectrum is limited by the …

In order to maximize the overall system throughput and cope with increasing user density
and traffic distribution as also limited spectrum availability in dense urban scenario, next …

Software-Defined Networking (SDN) has emerged as a new intelligent architecture for
network programmability. The primary idea behind SDN is to move the control-plane outside …

Driven by an exponential growth in mobile broadband-enabled devices and a continue
dincrease in individual data consumption, mobile data traffic has grown 4000-fold over the …

Résumé Ce travail s' inscrit dans le cadre d'une étude sur le déploiement et l'exploitation de
macros et micros cellules LTE. Du fait de l'augmentation exponentielle du trafic sur les …
