Problems solved by technology

[0003] Since the topology of WSNs is usually an aggregation mode, when multiple different sensor nodes send data to the same aggregation node, and the receiving rate of the aggregation node is higher than its own sending rate, the packet flow that the aggregation node needs to send exceeds its sending capacity. , the node-level congestion will occur at the sink node, resulting in buffer overflow, resulting in the loss of data packets and the increase of network queuing delay
[0004] The invention provides a transmission control method of the Internet of Things to solve the congestion problem of the convergence node

Embodiment Construction

[0031] An Internet of Things transmission control method, comprising the following steps:

[0032] Step S1, the data receiving sub-module of the transmission control module of the sink node device S receives the sensor node SN i Sent packet D SNij , and put the received packet D SNij Delivered directly to the data processing sub-module;

[0033] Among them, i is the serial number of the sensor node SN, i=1,2,…,n 1 ;

[0034] j is the data packet D SNi Sequence number of , j=1,2,…,n 2 ;

[0035] Step S2, the data processing sub-module of the transmission control module of the convergence node device S is responsible for processing the data packet D. SNij The specific processing method is as follows:

[0036] Step S2-1, according to the intrinsic attributes of the data, the data packet D is SNij Split into several sub-packets D SNij-J , and extract subpacket D SNij-J The file size of FS DSNij-J ;

[0037] Among them, J is the sub-packet D SNij Sequence number of , ...

Description

technical field [0001] The invention relates to the technical field of WSNs transmission control, in particular to an Internet of Things transmission control method, equipment and application in the Internet of Things networking. Background technique [0002] Wireless sensor networks (WSNs) are wireless networks composed of a large number of resource-constrained micro-sensor nodes randomly distributed in the detection area through self-organization and multi-hop. The sensor node is the basic unit of WSNs, mainly composed of sensing module, processing module, communication module, and energy supply module. The sensor node sends the collected data to the sink node (Sink) through wireless communication. It is other network communication methods that send data to the end user. [0003] Since the topology of WSNs is usually in the aggregation mode, when multiple different sensor nodes send data to the same sink node, and the sink node's receiving rate is higher than its own send...
