Hierarchical Multi-Agent DRL-Based Framework for Joint Multi-RAT Assignment and Dynamic Resource Allocation in Next-Generation HetNets

Autor: Alwarafy, Abdulmalik, Ciftler, Bekir Sait, Abdallah, Mohamed, Hamdi, Mounir, Al-Dhahir, Naofal

Publikováno v: IEEE Transactions on Network Science and Engineering, 2022

This paper considers the problem of cost-aware downlink sum-rate maximization via joint optimal radio access technologies (RATs) assignment and power allocation in next-generation heterogeneous wireless networks (HetNets). We consider a future HetNet

DQN-Based Multi-User Power Allocation for Hybrid RF/VLC Networks

Autor: Ciftler, Bekir Sait, Alwarafy, Abdulmalik, Abdallah, Mohamed, Hamdi, Mounir

In this paper, a Deep Q-Network (DQN) based multi-agent multi-user power allocation algorithm is proposed for hybrid networks composed of radio frequency (RF) and visible light communication (VLC) access points (APs). The users are capable of multiho

Effects of Solar Radio Emissions on Outdoor Propagation Path Loss Models at 60 GHz Bands for Access/Backhaul Links and D2D Communications

Autor: Sulyman, Ahmed Iyanda, Seleem, Hussein, Alwarafy, Abdulmalik, Humadi, Khaled M., Alsanie, Abdulhameed

This paper presents analytical and empirical data documenting the effects of solar radio emissions on outdoor propagation path loss at 60 GHz bands. Both line-of-sight (LOS) and non-LOS scenarios were considered. The setup used in the empirical studi

Directional Radio Propagation Path Loss Models for Millimeter-Wave Wireless Networks in the 28-, 60-, and 73-GHz Bands

Autor: Sulyman, Ahmed Iyanda, Alwarafy, Abdulmalik, MacCartney, George R., Rappaport, Theodore S., Alsanie, Abdulhameed

Fifth-generation (5G) cellular systems are likely to operate in the centimeter-wave (3-30 GHz) and millimeter-wave (30-300 GHz) frequency bands, where a vast amount of underutilized bandwidth exists world-wide. To assist in the research and developme
