Description

Low-power-consumption wireless communication networking method for Internet of things Technical Field The invention relates to the technical field of wireless networking of the Internet of things, in particular to a low-power consumption wireless communication networking method for the Internet of things. Background The existing low-power wireless networking technology of the Internet of things is widely applied to the scenes such as production line equipment state acquisition, warehouse environment monitoring, building electromechanical inspection, pipe gallery sensing and the like. Such techniques typically intermittently wake up the node by battery-powered means according to a preset sleep period, and complete data reporting, cache inquiry, hanging maintenance and acknowledgement reception within a wake-up window, so as to reduce the energy consumption pressure caused by the continuous online of the node. Aiming at networking maintenance, the existing scheme mostly adopts modes of fixed polling period, preset retransmission times, response confirmation of hanging nodes, cache forwarding maintenance and the like to maintain the communication relationship between the nodes and the superior access node, and can meet basic low-power consumption communication requirements under the conditions of more stable network environment and more uniform service arrival. However, in the actual deployment process, the running state of the low-power consumption node is not always in a stable working condition. On one hand, the conditions of equipment start-stop switching, door opening and closing, personnel and material shielding, local electromagnetic disturbance and the like often exist on site, so that the quality of a wireless link fluctuates in a short time, and on the other hand, the service born by a node does not always arrive uniformly, and short-time burst reporting can occur in the periods of alarming, interlocking, centralized inspection and the like besides periodic sampling. The prior art mostly focuses on single communication success rate, instantaneous link quality, or fixed retransmission policy, and is not sufficiently considered for continuous changes between node sleep rhythms, traffic arrival rhythms, and pending node response rhythms. In this way, when link fluctuation and traffic burst superposition occur, the node easily repeatedly performs early wakeup, shortens polling, repeatedly transmits, re-queries the buffer, and even frequently tries to maintain or adjust the hanging relationship, although a single action itself belongs to a conventional communication maintenance action, after continuous superposition, extra communication consumption is significantly increased, and the on-site group network state is unstable. Therefore, in the prior art, in the low-power consumption wireless networking scene, in the face of the running state of short-time fluctuation of a link and short-time burst concurrency of service, a networking maintenance mechanism capable of identifying and restraining the continuous communication rhythm of a surrounding node is lacked, so that invalid awakening, repeated polling, repeated retransmission and frequent hanging adjustment are easy to generate for the node, and further, the low-power consumption running requirement and the stable and reliable networking requirement are difficult to be simultaneously considered. Disclosure of Invention Aiming at the defects of the prior art, the invention provides a low-power consumption wireless communication networking method oriented to the Internet of things, which aims to solve the problems in the background art. In order to achieve the purpose, the invention provides the following technical scheme that the low-power consumption wireless communication networking method for the Internet of things comprises the following steps: s1, establishing a networking operation session aiming at a target low-power consumption node, and acquiring sleep time, wake-up time, polling time, service reporting time, leaning response time and retransmission records to generate networking rhythm characterization; s2, calculating polling hit deviation, hanging response delay deviation and business burst deviation according to the networking rhythm characterization, and determining the rhythm mismatch state of the target low-power consumption node; S3, generating a constrained communication token according to the rhythm mismatch state, the node residual capacity, the service priority and the reliability stability; S4, performing compensation wakeup, short-interval polling, limited retransmission, cache extraction and hanging detection according to the constrained communication token; s5, identifying invalid networking behaviors according to the execution record of each networking maintenance action, and applying inhibition restriction to the corresponding networking maintenance action in the next observation window; And S6, writing the rhythm mismatch state
