Problems solved by technology

In the past, it has been proved that using partially intersecting channels can obtain higher network capacity than orthogonal channels, so partially intersecting channels are used for allocation, but the advantages of using partially intersecting channels are not considered in essence.

Embodiment Construction

[0051] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0052] Such as figure 1 As shown, a multi-radio multi-channel wireless mesh network partial intersection channel allocation method includes the following steps:

[0053] S1. Calculate the number of neighbor nodes of each node and the distance between each node and the gateway node, and each node sends the number of neighbor nodes and the distance from the gateway node to the nodes within two hops of itself.

[0054] S2. Calculate the channel allocation priorities of all nodes, determine the order in which each node allocates channels, and arrange the priorities of each node in ascending order. The lower the priority of channel allocation, the higher the priority of the corresponding node.

[0055] In step S2, if the channel allocation prio...

Abstract

The invention discloses a multi-radio multichannel wireless mesh network portion intersection channel distribution method. The method comprises steps that, S1, neighbor node quantity of each node and distances from each node to a gateway node are calculated, the neighbor node quantity of each node and the distances from each node to the gateway node are sent by each node to nodes within two-hop scopes of each node; S2, channel distribution priorities of all nodes are calculated, channel distribution sequence of each node is determined, priority of each node is arranged in an ascending order, the smaller the channel distribution priority, the higher priority of the corresponding node; S3, channel distribution of each node is carried out according to the channel distribution priority; channel selection is carried out by each node; and S5, after channel distribution of each node, the channel distribution situation, communication nodes and the communication intensity of each node are sent to the nodes within two-hop scopes of each node. The method is applicable to cross channel scenes of multi-radio portions, can be applied to cross channel scenes of double-radio portions, requires no common channels and reduces radio cost.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for allocating partially intersecting channels of a multi-radio multi-channel wireless mesh network. Background technique [0002] In the wireless Mesh network, the interference model is divided into two different interference models: physical interference model and protocol interference model. In previous articles, for a multi-radio multi-channel network using orthogonal channels, the interference model generally adopts the traditional link-oriented thinking, that is, link interference model, link conflict diagram, and so on. This makes sense, because in a network using orthogonal channels, there is no interference between different channels. For example, in an IEEE802.11b / g network, the available orthogonal channels are only 1, 6, and 11. Therefore, in a multi-radio multi-channel network that generally uses orthogonal channels, the number of radio frequ...
