In this paper, we propose a fairness-based preemption algorithm for 3GPP LTE-Advanced. It considers bearers' priorities as well as their QoS over-provisioning with respect to their minimum QoS needs into the partial ...

The recent introduction of femtocells enabled high data rates and better coverage indoors without the need for upgrading the network infrastructure or site establishment. However, Femtocells may suffer from major interference ...

Distributed base stations are studied in the framework of LTE public safety networks. In the proposed model, users are connected to remote radio heads deployed throughout the cell and connected to a central base station. ...

In OFDM wireless networks, the radio resources are assigned to the users based on their quality of service needs and depending on their channel quality. Thus, during a call session, the bandwidth requirements and needed ...

Adoption of electric vehicles (EVs) is an important measure for greenhouse gas reduction in many countries worldwide. The increased production of EV in the market will be associated with continuous demand of installing and ...

Low switching frequency operation of multilevel inverter enables it for applications in high power processing needs. The stepped waveform synthesized from multilevel inverter after Fourier series analysis will result in ...

Induction motors turn out to be the economical workhorses in the industry for the AC motor drive application. To satisfy the steady-state and transient performance specification of AC drives, control techniques are required ...

Low terminal voltage at the output of a solar photovoltaic needs efficient boost converters for establishing a proper communication and energy transfer to the DC microgrids. In order to serve this purpose, the traditional ...

The advantages of multilevel inverter over traditional inverter mainly for high power applications are very high. Due to increase in voltage level, the multilevel technology is very attractive for high power application ...

In a DC microgrid, the integration of renewable energy sources requires a DC-to-DC converter for a better communication and energy transfer. The conventional boost converter endures many snags owing to its operation at an ...
