In this book, a solution for fixing the power problem in the wireless sensor and actuator networks is proposed. The method was proposed as research to get a master's degree in computer engineering, and I produced an algorithm for recharging or replacing the nodes that suffer from low power problems by taking advantage of the actuators' movement in the wireless sensor and actuator networks. This method does not require additional costs and is a permanent solution to the power problem of wireless sensor and actuator networks.
