Self-adaptive heartbeat method and system based on distribution

Abstract

The invention relates to a self-adaptive heartbeat method used for maintaining internet of things equipment connection and based on distribution. The method comprises the following steps: the internetof things equipment establishes and maintains the network connection with an internet of things cloud platform through a belonged local area network and initializes a self-adaptive parameter; the internet of things equipment sends self-adaptive parameter request broadcast to the belonged local area network, and updates the self-adaptive parameter and self-adaptive heartbeat period according to the self-adaptive parameter sharing broadcast responded by other equipment in the local area network; multiple detection values needing to perform the detection are determined through exponential growthway or linear growth way, and these detection values are divided into multiple period detection tasks to distribute to multiple internet of things equipment in the local area network to perform the detection. By using the self-adaptive heartbeat method disclosed by the invention, the problems of multiple detection frequencies and long time-consuming in the self-adaptive heartbeat period process of the internet of things equipment are solved, and an efficient detection termination strategy is provided for balancing the detection error and detection efficiency.

Description

technical field [0001] Aiming at the problem of maintaining the network connection of Internet of Things devices, the present invention proposes a distributed-based self-adaptive heartbeat method, and obtains an optimal heartbeat period through cooperation among Internet of Things devices in the same local area network. Background technique [0002] With the gradual maturity and practicality of IoT horizontal access protocols (such as CoAP, MQTT, LwM2M, EBHTTP, etc.), connect devices to cloud platforms (such as Xively, Watson IoT, OneNET, YeeLink, etc.) to access devices in real time Gradually become a mainstream architecture. [0003] Due to the limitations of existing Internet infrastructure (such as limited IP address and port resources), most IoT devices are usually located in corporate LANs or home LANs, without independent public IPs, and need to use network address translation (NAT) A network connection is established through port mapping to connect to the Internet. ...
