Coverage-Aware Recharge Scheduling Scheme for Wireless Charging Vehicles in the Wireless Rechargeable Sensor Networks

摘要

Recent advancement in the wireless power transfer technology has motivated the development of a wireless rechargeable sensor network (WRSN). In WRSNs, the formation of an optimal recharging schedule for each wireless charger vehicle is a well known NP-complete problem. To determine the optimal recharging schedule for each wireless charger vehicle, this paper presents a coverage-aware recharge scheduling scheme (CRS) where ACO-based metaheuristic algorithm is employed. In order to provide fast recharging in WRSN, the proposed scheme employs multiple wireless charger vehicles to perform the charging task. Performance analysis of the proposed scheme confirms its superiority in terms of charging latency.
