Andreas Nicolaides


Andreas Nicolaides studied Electrical and Computer Engineering at the National Technical University of Athens, Greece, where he specialized in Communications and Networking and graduated with a five-year Diploma in 2019. He is currently a PhD student in the Department of Electrical and Computer Engineering at the University of Cyprus and a Researcher at the IRIDA Research Centre for Communication Technologies. His research interests focus on wireless communications and wireless power transfer (WPT). In the PAINLESS project he will work on the topic of cooperative networks and multi-hop relaying systems and their utilization in wireless powered backscattering communications.

Wireless Power Transfer (WPT) in cooperative multi-hop relaying networks

A cooperative protocol is investigated for a multi-hop network with buffers of finite size at the relay nodes. The protocol is based on the -hop myopic decode-and-forward (DF) coding strategy. Each relay stores in its buffer the messages that were successfully decoded and the transmission of the decoded signals is adapted, according to the status of the buffers. A complete theoretical framework has been investigated that models the evolution of the buffers as a state Markov chain (MC). Our results show that as the degree of cooperation among neighboring nodes increases, the performance of the system is enhanced both in terms of outage probability and diversity gain
