Method for setting up chained mode wireless network and network nodes therefor

Abstract

The embodiment of the invention provides a method for setting up a chained mode wireless network and network nodes therefor, which are applicable to a wireless networking comprising multiple network nodes. The method comprises the following steps: choosing an available channel as a working channel of a current first network card; measuring signal intensity of all first network cards expect the current first network card and obtaining the measurement result and determining all neighboring nodes of a current network node according to the measurement result; transmitting the neighbor list of thecurrent network node to all neighboring nodes to obtain the neighbor list of all network nodes in the wireless network; carrying out route calculation according to the neighbor list to obtain all network nodes in the wireless network and loop-free connecting routes; wherein the current network node is connected to the wireless network according to the connecting routes. The embodiment of the invention can form a chained mode network featuring high efficiency transmission when wireless signal intensity between 'neighboring' nodes can not accurately reflect physical adjacency.

Description

technical field [0001] The invention relates to a multi-interface wireless network automatic channel allocation and link building method, in particular to a chain wireless network building method and a network node. Background technique [0002] In daily life, there is a long chain-like environment, such as tunnels, trains, promenades, etc. With the popularization of broadband wireless networks, people often use wireless networks in the chain-like environment. Therefore, Establishing an efficient broadband wireless chain access network adapted to the chain environment will be extremely important for people living in the chain environment to enjoy broadband services. [0003] In addition, with the gradual reduction in the cost of wireless access equipment and the sharp increase in people's demand for broadband, the past mode where each access point only contains one wireless interface has become the bottleneck of the wireless network. The entry point has been recognized by t...

Problems solved by technology

[0007] The purpose of the embodiments of the present invention is to provide a method for building a chained wireless network and network nodes, which can form a chained network with high-efficiency transmission, and solve the problem that the wireless signal strength between "neighbor" nodes cannot be accurately reflected in the prior art. In the case of physical adjacency, it is impossible to form a chain network for efficient transmission.
