On the Secrecy Performance and Power Allocation in Relaying Networks with Untrusted Relay in the Partial Secrecy Regime
Diana P. M. Osorio, Hirley Alves, Edgar E. B. Olivo
Recently, three useful secrecy metrics based on the partial secrecy regime were proposed to analyze secure transmissions on wireless systems over quasi-static fading channels, name…
Massive Wireless Energy Transfer: Enabling Sustainable IoT Towards 6G Era
Onel L. Alcaraz López, Hirley Alves, Richard Demo Souza +3
Recent advances on wireless energy transfer (WET) make it a promising solution for powering future Internet of Things (IoT) devices enabled by the upcoming sixth generation (6G) er…
Dynamic Multi-Connectivity Activation for Ultra-Reliable and Low-Latency Communication
Nurul Huda Mahmood, Hirley Alves
Multi-connectivity (MC) with packet duplication, where the same data packet is duplicated and transmitted from multiple transmitters, is proposed in 5G New Radio as a reliability e…
Rate Control for Wireless-Powered Communication Network with Reliability and Delay Constraints
Onel L. Alcaraz López, Hirley Alves, Richard Demo Souza +2
We consider a two-phase Wireless-Powered Communication Network under Nakagami-m fading, where a wireless energy transfer process first powers a sensor node that then uses such ener…
Distributed Rate Control in Downlink NOMA Networks with Reliability Constraints
Onel L. A. López, Hirley Alves, Matti Latva-aho
Non-orthogonal multiple access (NOMA) has been identified as a promising technology for future wireless systems due to its performance gains in spectral efficiency when compared to…
Achieving Ultra-Reliable Communication via CRAN-Enabled Diversity Schemes
Binod Kharel, Onel L. Alcaraz López, Hirley Alves +1
Internet of things is in progress to build a smart society, and wireless networks are critical enablers for many of its use cases. In this paper, we present a multi-coordinated tra…
