A communication method and device for the internet of things

Abstract

Embodiments of the invention disclose an Internet-of-things communication method and an Internet-of-things communication device. The method comprises the following steps: generating a forwarding table of sensor nodes in a tree topology structure of the Internet of things, wherein the forwarding table includes the time information and space information of sensed data, the time information is a Unix timestamp corresponding to the sensed data, and the space information is latitude and longitude corresponding to the sensed data; acquiring a to-be-sent request of the current sensor node, wherein the to-be-sent request is a request which is sent by a request node in communication connection with the current sensor node in the tree topology structure of the current sensor node and contains a request data packet, and the request data packet carries corresponding time information and latitude and longitude; and responding to the to-be-sent request according to the forwarding table. According to the embodiments of the invention, a data packet in the Internet of things is simpler in structure and is more suitable to be processed by a sensor node with limited ability, and the stability of the entire Internet of things is improved.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a communication method and device for the Internet of Things. Background technique [0002] The Internet of Things is the use of communication technologies such as local networks or the Internet to connect sensors, controllers, machines, people and things together in a new way, forming a connection between people and things, things and things, and realizing informatization and remote management and control. and intelligent network. The Internet of Things is an extension of the existing information network to the physical world. It believes that objects in the physical world, whether people or objects, are also participants in the information world. They have the ability to generate data and exchange data between each other. , thereby affecting the surrounding environment. [0003] In the current research on the architecture of the Internet of Things, it is...

Problems solved by technology

However, the processing power and storage capacity of sensor nodes in the Internet of Things are still very limited

Existing data-centric network construction methods usually contain a large amount of routing information, which undoubtedly increases the processing pressure on sensor nodes. Therefore, once the network environment changes, a large amount of routing information will cause sensor nodes to be unable to process it, resulting in information transmission. Unsmooth, causing the entire IoT network to fail
