Abstract

The invention relates to a mobile energy supplement method for a wireless sensor and actuator network, and belongs to the research field of prolonging the lifetime of wireless sensor and actuator networks by using a wireless charging technology. The wireless sensor and actuator network has the advantages of perceiving, timely responding to and acting on the environment and the like. However, bothof the sensor and the actuator serving as core components of the network face the problem of energy constraint, which seriously restricts the lifetime of the network. Current work only considers the energy supplement problem of wireless sensor networks, but has not yet considered the energy supplement problem of wireless sensor and actuator networks that incorporate actuators with mobile and executive functions. The method well adapts to autonomous motion and long charging time of the actuators in the wireless sensor and actuator networks and high dynamic energy consumption characteristic caused in response to emergencies, and can ensure the energy supply of the actuators in the networks, simultaneously reduce the failure rates of sensor nodes as much as possible and maintain the long-termcontinuous operation of the entire networks.

Description

technical field [0001] The invention relates to a mobile energy replenishment method for a wireless sensor and actuator network, and belongs to the research field of prolonging the lifetime of the wireless sensor and actuator network by using wireless charging technology. Background technique [0002] Wireless Sensor and Actuator Networks (Wireless Sensor and Actuator Networks, WSAN) consists of randomly deployed sensor nodes, a certain number of actuator nodes, base stations and mobile charging devices. Among them, the sensor node has the advantages of low cost, low power consumption, perception, data processing and wireless communication capabilities. It can sense and monitor heat, infrared, fire and earthquake signals in the surrounding environment, and can detect the temperature and humidity of the environment. , noise, and soil composition events. Actuators have stronger communication and data processing capabilities, and can perform tasks autonomously. Executors make...
