Journal ArticleDOI
Distributed wireless power transfer in sensor networks with multiple Mobile Chargers
TL;DR: Four new protocols for efficient charging are proposed, addressing key issues which are identified, most notably (i) what are good coordination procedures for the Mobile Chargers and (ii) what is good trajectories for the mobile Chargers.
Journal ArticleDOI
Data Management in Industry 4.0: State of the Art and Open Challenges
TL;DR: In this paper, a survey of the recent literature on data management as it applies to networked industrial environments and identifies several open research challenges for the future is presented, motivated by the rich conclusions of this critical analysis, and select interesting open challenges for future research.
Journal ArticleDOI

Constantinos Marios Angelopoulos,Sotiris Nikoletseas,Theofanis P. Raptis,Theofanis P. Raptis +3 more
TL;DR: Three new, alternative protocols for efficient charging are proposed, addressing key issues which are identified, most notably to what extent each sensor should be charged, and what is the best split of the total energy between the charger and the sensors.
Journal ArticleDOI
Hierarchical, collaborative wireless energy transfer in sensor networks with multiple Mobile Chargers
TL;DR: This work enhances the collaborative feature by forming a hierarchical charging structure, and proposes and implements four new collaborative charging protocols for 2-D networks, in order to achieve efficient charging and improve important network properties.
