Abstract

The invention discloses a channel allocating method and a device for a multichannel multi-interface wireless mesh network, relating to the wireless mesh network. The channel allocating method comprises the following steps: determining a trunk node in a broadcast tree after generating the broadcast tree from all nodes in the wireless mesh network according to grades, constructing a multicast tree with the least number of nodes according to the trunk node, and performing channel allocation for each node in the constructed multicast tree. By using the technical scheme of the invention, the network throughout is improved to a large extent and the time delay is lowered.

Description

technical field

[0001] The invention relates to a wireless mesh network (Wireless Mesh Network), in particular to a channel allocation method and equipment for a multi-channel multi-interface wireless mesh network. Background technique

[0002] Wireless Mesh Network (WMN, Wireless Mesh Network, also known as wireless mesh network, wireless mesh network, etc.), is a new type of broadband wireless mesh structure, a high-capacity, high-speed distributed mesh. In terms of network topology, the wireless Mesh network is similar to the Ad Hoc network, but the user terminals of the wireless Mesh network have relatively low mobility, and most nodes in the network are basically stationary, without batteries as power, and the topology changes are small. Furthermore, the wireless mesh network generally does not exist as an independent network form, but is a wireless extension of the Internet core network. The main business of the nodes of the wireless mesh network is the business to and...
