Joint Power Charging and Routing in Wireless Rechargeable Sensor Networks [PDF]

Sensors, 2017
The development of wireless power transfer (WPT) technology has inspired the transition from traditional battery-based wireless sensor networks (WSNs) towards wireless rechargeable sensor networks (WRSNs). While extensive efforts have been made to improve charging efficiency, little has been done for routing optimization.
