Problems solved by technology

[0006] It realizes a new transaction method by combining the decentralization technology of the Internet of Things and the blockchain, but the decentralized network can only conduct data transactions
At the same time, when the structure of the Internet of Things changes, it is impossible to adjust the decentralized network in real time, resulting in increased maintenance costs and reduced applicability

Embodiment 1

[0030] like figure 1 As shown, the construction method of the decentralized sensor network of the Internet of Things, the method performs the following steps:

[0031] Step 1: interconnect multiple sensor network clusters in the Internet of Things to form a decentralized network cluster; the sensor network clusters include two types: use network clusters and vacant network clusters; the sensor network clusters include: cluster head nodes , the nodes in the cluster and the new nodes; the nodes in each cluster in the sensor network cluster are interconnected to each other to form an intranet within the cluster, and the cluster head nodes are interconnected to each other to form an internal and external network of the cluster; The signal connection between them; the new node includes: a node in the cluster and a cluster head node; the node in the cluster in the new node will automatically join the intranet in the cluster to form a node in the intranet in the cluster, and the clus...

Embodiment 2

[0039] On the basis of the previous embodiment, the cluster head node is a full-featured node with routing forwarding function, which is a component of the backbone network; the intra-cluster node is a partial functional node without routing forwarding function, used for data collection; The new node is a full-function node or a part-function node that is not marked as a cluster head node or a node in the cluster; some function nodes do not have routing and forwarding functions.

Embodiment 3

[0041] On the basis of the previous embodiment, the step 2 includes: when the function of the Internet of Things changes, a control command is generated according to the change of the function; the change of the function includes: the addition of the function of the Internet of Things, The function of the Internet of Things is reduced and the function of the Internet of Things is changed; when the function of the Internet of Things is added, a new control command is generated to the vacant network cluster in the sensor network cluster of the Internet of Things. Some of the nodes in the nodes are converted into nodes in the cluster; when the function of the Internet of Things is reduced, a reduction control command is generated to use the network cluster in the sensor network cluster of the Internet of Things, and the network cluster is used to reduce the nodes in the cluster according to the received reduction control command Part of the nodes in the network are converted into ...

Abstract

The invention belongs to the technical field of the Internet of Things, and particularly relates to a method and system for constructing a decentralized sensor network of the Internet of Things. The method comprises the following steps: enabling a plurality of sensor network clusters in the Internet of Things to be mutually connected to form a decentralized network cluster; the sensor network cluster has two types of a used network cluster and a vacant network cluster and comprises a cluster head node, an intra-cluster node and a new node; the in-cluster nodes in the sensor network cluster are mutually interconnected to form an in-cluster intranet, and cluster head nodes are mutually interconnected to form a cluster intranet and a cluster intranet; and the intra-cluster intranet and the intra-cluster intranet are in signal connection. According to the method, the Internet of Things is subjected to multi-layer layering, the layered Internet of Things can be subjected to function maintenance better, and when new functions need to be added, reduced or changed, automatic adjustment can be carried out; and meanwhile, by scheduling the data in the layered network, the efficiency of the Internet of Things and operation is improved.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, and in particular relates to a method and system for constructing a decentralized sensor network of the Internet of Things. Background technique [0002] The Internet of Things (IOT) refers to the real-time collection of any information that requires monitoring, connection, and interaction through various devices and technologies such as information sensors, radio frequency identification technology, global positioning system, infrared sensors, and laser scanners. Objects or processes, collect various required information such as sound, light, heat, electricity, mechanics, chemistry, biology, location, etc., and realize the ubiquitous connection between objects and objects, objects and people through various possible network accesses, Realize intelligent perception, identification and management of items and processes. The Internet of Things is an information carrier based on the ...
