Wireless power transfer (WPT) prolongs the lifetime of wireless sensor network by providing sustainable supply to distributed nodes (SNs) via electromagnetic waves. To improve energy efficiency in a large WPT system, this paper proposes an adaptively directional (AD-WPT) scheme, where beacons (PBs) adapt beamforming strategy SNs' locations concentrating transmit on nearby SNs within efficient charging radius.
