For conventional wireless networks, the main target of resource allocation (RA) is to
efficiently utilize the available resources. Generally, there are no changes in the available …

Traditional spectrum allocation policies may result in temporarily unused radio spectrum.
Cognitive radio (CR) has emerged as a promising technology to exploit the radio spectrum …

In order to mitigate the shortage of wireless spectrum, the appealing concepts of cooperative
communication techniques and cognitive radio (CR) networks have been combined for the …

In this paper, a novel framework is proposed to jointly optimize user association and
resource allocation in the uplink cognitive femtocell network (CFN). In the considered CFN …

Ultra-dense networks are envisioned as essential to embrace the skyrocketed traffic for the
next-generation wireless networks. In this paper, we consider the uplink transmissions in …

For the current 5G era, the deployment of small cells in residential and commercial areas
plays an imperious preamble in improving network coverage and the quality of service …

This study proposes a multiobjective beamforming power control scheme to achieve the
robust quality of service (QoS), the optimal signal-to-interference-plus-noise ratio (SINR) …

In this paper, we study distributed power allocation for multiflow carrier aggregation in
cognitive cellular networks. Our approach differs from the conventional water filling (WF) …

Next generation cellular networks will consist of multiple tiers of cells and users associated
with different network tiers may have different priorities (eg, macrocell-picocell-femtocell …

Effective radio frequency spectrum sharing methods are crucial for sustaining growth and
development in mobile wireless services. In this paper, we consider a real-world scenario …
