Joint Optimization of Charging Location and Time for Network Lifetime Extension in WRSNs

IEEE Transactions on Green Communications and Networking, 2022
Wireless rechargeable sensor networks (WRSNs) have emerged as a potential solution to solve the challenge of prolonging battery-powered sensor networks’ lifetime. In a WRSN, a mobile charger moves around and charges the rechargeable sensors when stopping at charging spots. This paper newly considers a joint optimization of the charging location and the

Q-learning-based, Optimized On-demand Charging Algorithm in WRSN

2020 IEEE 19th International Symposium on Network Computing and Applications (NCA), 2020
This paper introduces a novel charging strategy for wireless rechargeable sensor networks (WRSNs), in which a mobile charger (MC) moves and wirelessly transfers the power to the sensor nodes. The first distinct point of this work is designing the MC's charging algorithm under the consideration of target coverage and connectivity.
