A wireless mesh network channel allocation method, device and electronic equipment

Abstract

Embodiments of the present invention provide a wireless mesh network channel allocation method, device, and electronic equipment, wherein the method includes: judging whether the current node is the central node of the topology structure of the wireless mesh network; obtaining network status information of the wireless mesh network; using wireless The network status information of the wireless mesh network and the first preset formula determine the link weight of each link in the wireless mesh network; use the network status information of the wireless mesh network and the second preset formula to determine the link weight of each link in the wireless mesh network The conflict coefficient of the link pair composed of links; for each link, take the intersection of the available channel sets of the two end nodes of the link to obtain the available channel set of the link; for each link, use The conflict coefficient of the link pair of the link, the link weight of the link and the available channel set of the link determine the target channel of the link when the current network conflict function is minimized.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a wireless mesh network channel allocation method, device and electronic equipment. Background technique [0002] A Wireless Mesh Network (WMN) is a broadband network that can be used to access the Internet, and it has the characteristics of high capacity and high speed. It consists of wireless nodes distributed in a mesh, and realizes the interconnection and intercommunication between nodes through adaptive node discovery, topology maintenance and multi-hop forwarding. Wireless Mesh network is a special mobile ad hoc network, which inherits some of the characteristics of wireless local area network technology, which is equivalent to the fusion of WLAN (Wireless Local Area Networks, wireless local area network) and Ad Hoc network technology, and has these two technologies The advantages. The design purpose of the wireless Mesh network is to enable all nodes in the networ...

Although the widely used IEEE802.11a protocol theoretically has a peak rate of 54Mb / s, in reality, due to various factors such as packet loss and collisions when multiple users access, the actual usable rate is only about One-half of the peak value greatly limits the data transmission rate of the network and the total capacity of the entire network, resulting in the failure of some data services with relatively high bandwidth requirements to be transmitted in the network
