[Retracted] Mixed Linear Programming for Charging Vehicle Scheduling in Large‐Scale Rechargeable WSNs

Journal of Sensors, Volume 2022, Issue 1, 2022., 2022
Because wireless sensor networks (WSNs) have low‐constrained batteries, optimizing the network lifetime is a primary challenge. Rechargeable batteries are a solution to prolong the lifetime of a sensor node instead of restricting their functionalities to save energy.
