Joint Source and Relay Beamforming Design in Wireless Multi-Hop Sensor Networks with SWIPT

open access: yesSensors, 2019
We consider a multiple-input multiple-output amplify-and-forward wireless multiple-hop sensor network (WMSN). The simultaneous wireless information and power transfer technology is deployed to potentially achieve an autonomous system.
