RIS-carried UAV communication: Current research, challenges, and future trends

ICT Express, 2023
Enhanced quality of service (QoS) and resource allocation are important measurements in a mobile communication system. Compared to traditional mobile networks, 6G uses spectrum from 0.3 to 3 terahertz (THz) and millimeter wave (mmWave) from 30 to 300 GHz

A Layered Subtree Scheme for Multicast Communications in Large-Scale Elastic Translucent Optical Networks

IEEE Access, 2020
To exploit the capacity introduced by elastic optical networks, efficient algorithms must be developed. Efficient modulation techniques have limited reach, so for distant destination nodes, the regeneration of a signal at a few intermediary nodes along ...
