Embodiment 1

[0024] figure 1 It is a schematic flow diagram of a method for data transmission of the Internet of Things provided by Embodiment 1 of the present invention, as shown in figure 1 As shown, the Internet of Things data transmission method includes the following steps:

[0025] 101. The network node mixes various types of data corresponding to the same application to obtain mixed data.

[0026] Specifically, the network node receives data sent by different data collection devices, such as sensors, etc. After receiving the data sent by each data collection device, the network node can obtain the application corresponding to each data from the received data. The network node mixes various types of data corresponding to the same application to obtain mixed data. For example, a network node may encapsulate various types of data of the same application into a data packet.

Abstract

The invention provides a data transmission method for the Internet of Things and a network node. The data transmission method for the Internet of Things comprises the steps that the network node mixes various types of data corresponding to the same application, so that mixed data are obtained, the network node obtains the complexity of the mixed data, the network node selects one of paths corresponding to the application to serve as a target path, the network node obtains the transmission cost of the target path according to the complexity, the network node judges whether the transmission cost is smaller than a preset threshold value, and the network node transmits the mixed data according to the target path if yes. According to the data transmission method for the Internet of Things and the network node, the network node obtains the complexity of the mixed data, so that the target path with the transmission cost smaller than the preset threshold value is selected for the mixed data, the purpose of self-adaptive selection of the target path for the mixed data is achieved, the mixed data transmission cost can be reduced by transmitting the mixed data through the target path, and thus route resources can be saved.

Description

technical field [0001] The invention relates to the Internet of Things technology, in particular to a data transmission method of the Internet of Things and a network node. Background technique [0002] The Internet of Things is divided into a perception layer, a transport layer (that is, a network layer), a processing layer, and an application layer. Data acquisition devices in the Internet of Things, such as infrared sensors, radio frequency identification (Radio Frequency Identification, referred to as RFID) devices, or two-dimensional barcodes, etc., obtain the physical characteristics of objects through perception, such as temperature, location and other information, and then convert the perceived information into Send data to applications in the Internet of Things, such as intelligent transportation, identity authentication, location-based services and security, so that applications can use these data to provide users with various services. [0003] At present, after ...
