A node networking method applied to a high-density multi-hop network

Abstract

The invention discloses a node networking method applied to a high-density multi-hop network. The method comprises the following steps: a central controller serving as a root node broadcasts beacon frames to nodes in a one-hop range of the root node; After receiving the beacon frame, the one-hop node returns an access request frame to the central controller; the central controller judges whether the one-hop node meets the network access requirement or not; judging whether the node meeting the network access requirement is a relay node or not; polling the one-hop relay node to enable the two-hop node to access the network; selecting a relay node in the two-hop network access node to continue polling; The networking efficiency is effectively improved through selection of relay nodes in the multi-hop network, the multi-hop node networking process, information storage and the like, so that the purposes of improving the node networking efficiency in a high-density environment and improvingthe response time of the nodes are achieved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a node networking method applied in a high-density multi-hop network. Background technique [0002] With the rise of the Internet of Things industry, smart home appliances have gradually entered people's lives. How to quickly network smart devices is a hot technical point of current research. At present, the smart terminal is connected to the smart home node through a dedicated control node (central controller CCO), and then the control node forwards the instructions of the smart terminal to other smart home nodes. [0003] In a wireless multi-hop network, there may be multiple relay nodes between the source node and the destination node. Therefore, a node in a multi-hop network has two functions, that is, the node can act as a terminal node to generate or receive data packets, and the node can also act as a relay node to store and forward data packets of other nod...

Problems solved by technology

In this standard, the abbreviation of the central control coordinator, the proxy controller, and the networking behavior of the device are given in the process of single-network networking, but in general, the description of this specification is rough, and in particular, no specific implementation details are involved.

In actual engineering implementation, we should not only consider the realization of functions, but also consider the production and sales of equipment, as well as the cost of operation and maintenance in the later period, as well as the low efficiency of networking and slow response time in high-density environments.
