Abstract

The invention belongs to the technical field of sensors, and particularly relates to a wireless sensor network node awakening system and method based on a way-finding algorithm, and the system comprises an active awakening center, wireless sensor nodes, and a sensor network. The wireless sensor nodes are irregularly distributed in a sensor network; each wireless sensor node comprises a central control unit, an active wake-up control unit, a passive wake-up control unit and a sensor. The active awakening control unit responds to an awakening command of the active awakening center and awakens the sensor node; and the passive awakening control unit awakens the sensor node under the control of a preset triggering condition of the central control unit. Through the combination of a passive awakening mode and an active awakening mode, the power consumption of the sensor network is reduced, and the service life of the sensor network is prolonged; meanwhile, the path finding method based on thegenetic algorithm enables the sensor awakening efficiency to be higher, and reduces the probability of false awakening.

Description

technical field

[0001] The invention belongs to the technical field of sensors, and in particular relates to a wireless sensor network node wake-up system and method based on a pathfinding algorithm. Background technique

[0002] With the rapid development of the Internet of Things technology, its application in various fields is becoming more and more extensive, and wireless communication technology, as one of the main communication technologies of the Internet of Things, is also more and more widely used. , have put forward very high requirements for the low power consumption and long-distance transmission of the wireless communication system. A general wireless communication system is mainly composed of a master node and multiple slave nodes.

[0003] In the traditional technology, the wireless communication system adopts a periodic wake-up mechanism to reduce power consumption. After the slave node wakes up automatically within the wake-up period, it is ready to receive...
