Self-organized networking method based on low-rate wireless network

Abstract

The invention discloses a self-organized networking method based on a low-rate wireless network. The self-organized networking method comprises the following steps: step 1, nodes in a network to be organized are numbered; step 2, a node is selected as a networking origination node; step 3, the networking origination node searches for primary nodes; step 4, whether all the nodes can be taken as the primary nodes is judged, and if so, networking is finished, otherwise, the next step is started; step 5, the networking origination node delegates subordinate nodes thereof to search for secondary nodes corresponding to every subordinate node; and step 6, whether all the nodes are already in superior-and-subordinate communication connection with the networking origination node is judged, and if so, networking is finished, otherwise, the step 5 is carried out again. The self-organized networking method based on the low-rate wireless network, when applied to the organization of the low-rate wireless network, does not cause network congestion and is capable of greatly reducing the probability of network concurrent storms.

Description

technical field [0001] The invention relates to the field of wireless low-rate network communication, in particular to an ad hoc network method based on a low-rate wireless network. Background technique [0002] At present, Wi-Fi technology and 6LowPAN technology are often used in wireless network networking. Among them, Wi-Fi technology adopts star topology, and the network coverage is the signal coverage of the wireless router. 6LowPAN is currently the most promising wireless networking technology, and because it supports IPV6, it is predicted to be the only way for the Internet of Things to eventually unify. [0003] In low-speed wireless network networking, limited by power consumption requirements, the communication distance between single points is often limited to about 50 meters. If the wireless topology of Wi-Fi technology is used, the communication distance of the backbone nodes must be far enough , the Wi-Fi technology of the star topology is obviously not applic...

AI Technical Summary

Problems solved by technology

When 6LowPAN technology is applied to low-power wireless network networking, due to the low transmission rate of the low-power wireless network itself, most of the time there is not much data traffic. At this time, there is still a large amount of network maintenance data circulating in the entire network. When a large amount of data is transmitted, the network maintenance data packets will not stop, which will lead to the simultaneous transmission of a large number of data packets, concurrent wireless signals will lead to channel congestion, and channel congestion will cause the network data packets to fail to be transmitted, network stability will deteriorate, and even cause network crash

Therefore, 6LowPAN technology is obviously not suitable for low-power wireless network networking
