Beam with Adaptive Divergence Angle in Free-Space Optical Communications for High-Speed Trains
Yagiz Kaymak, Sina Fathi-Kazerooni, Roberto Rojas-Cessa +4
In this paper, we propose an adaptive beam that adapts its divergence angle according to the receiver aperture diameter and the communication distance to improve the received power…
NOMA Aided Narrowband IoT for Machine Type Communications with User Clustering
Ali Shahini, Nirwan Ansari
To support Machine Type Communications (MTC) in next generation mobile networks, NarrowBand-IoT (NB-IoT) has been released by the Third Generation Partnership Project (3GPP) as a p…
A Hybrid RF-VLC System for Energy Efficient Wireless Access
Abdallah Khreishah, Sihua Shao, Ammar Gharaibeh +3
In this paper, we propose a new paradigm in designing and realizing energy efficient wireless indoor access networks, namely, a hybrid system enabled by traditional RF access, such…
Energy Efficient Resource Allocation in EH-enabled CR Networks for IoT
Ali Shahini, Abbas Kiani, Nirwan Ansari
With the rapid growth of Internet of Things (IoT) devices, the next generation mobile networks demand for more operating frequency bands. By leveraging the underutilized radio spec…
Hierarchical Capacity Provisioning for Fog Computing
Abbas Kiani, Nirwan Ansari, Abdallah Khreishah
The concept of fog computing is centered around providing computation resources at the edge of network, thereby reducing the latency and improving the quality of service. However,…
Distributed Energy and Resource Management for Full-Duplex Dense Small Cells for 5G
Animesh Yadav, Octavia A. Dobre, Nirwan Ansari
We consider a multi-carrier and densely deployed small cell network, where small cells are powered by renewable energy source and operate in a full-duplex mode. We formulate an ene…
