In order to achieve the above object, the present invention provides a fast saturation algorithm in a wireless sensing layer network of the internet of things, which includes the following steps:
s1, the concentrator establishes wireless connection with the terminal sub-nodes connected with the concentrator, the concentrator sends out a wake-up instruction to the terminal sub-nodes connected with the concentrator, and the awakened terminal sub-nodes store instruction contents and father node ID numbers and enter a sleep state after forwarding a broadcast command outwards; the awakened terminal sub-node must send out a broadcast command and can only send out the broadcast command once, and the command content is transmitted out;
s2, the terminal sub-node which receives the broadcast command enters a sleep state if the broadcast command is sent out once; if the broadcast command is not sent out, the broadcast command must be sent out once, the instruction content is transmitted out, and then the sleep state is entered;
s3, judging whether all terminal sub-nodes enter the sleep state, if all terminal sub-nodes enter the sleep state, indicating that all terminal sub-nodes have received the command sent by the concentrator, executing the step S4, otherwise returning to the step S2;
and S4, all terminal child nodes receiving the broadcast command transmit the processing result back to the concentrator through the respective unique parent node.
The rapid saturation algorithm in the wireless sensing layer network of the Internet of things enables traversal instructions issued by the concentrator to be rapidly and accurately transmitted to each managed terminal (as long as no isolated node exists in sensing layer nodes, namely, peripheral nodes without communicable nodes are called isolated nodes). Thereby being not influenced by environmental factors such as house type, structure, height, sealing performance and the like.
In a preferred embodiment of the present invention, the steps S2 and S3 may be:
s2, the terminal sub-node which receives the broadcast command enters a sleep state if the broadcast command is forwarded outwards once; if no broadcast command is sent outwards, part or all of the terminal sub-nodes send out a broadcast command once and transmit the instruction content;
s3, judging whether all terminal sub-nodes enter the sleep state, if all terminal sub-nodes are in the sleep state, executing the step S4, otherwise returning to the step S2.
And part or all terminal sub-nodes can send out broadcast calls, and all nodes are ensured to be awakened on the premise of reducing the power consumption as much as possible.
In another preferred embodiment of the present invention, the broadcast command is a non-targeted broadcast command. Ensuring that all terminal sub-nodes are awakened.
In another preferred embodiment of the present invention, each terminal sub-node can and cannot only make one outgoing broadcast call during one wake-up. Only one broadcast call can be sent out, thus preventing the self-excitation between nodes.
In another preferred embodiment of the present invention, the broadcast command includes a broadcast wakeup call and a broadcast command that needs to be executed by a public node and is sent at the same time, and the terminal child node that is waken wakes up stores the content of the command and the ID number of the parent node after waking up, and forwards the broadcast command using the ID number of the local node as the calling party once.
And when the broadcast is awakened, the broadcast instruction is transmitted at the same time, so that the data recovery speed and efficiency are improved.

Thereby stopping the operation of the issue terminal.
In this embodiment, the broadcast command includes a broadcast wakeup call and a broadcast command that needs to be executed by a public node and is sent at the same time, and the terminal child node that is waken wakes up stores the command content and the parent node ID number and forwards the broadcast command using the node ID number as the calling party once.
