Embodiment Construction

[0054] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0055] Such as figure 1 As shown, after the equipment of the present invention is networked, an improved method is proposed to solve the problem that the traditional algorithm uses the remaining air interface to evaluate the multi-hop transmission capability, and the present invention includes the following steps:

[0056]Each device will receive routing management frames from other devices. The direction of the routing management frame is from the target device to the source device. The information carried by the routing management frame includes: the maximum transmission capacity information of each path, the maximum transmission capacity information For the corresponding channel and / or the remaining air interface information of the channel, the source device judges whether the path has passed through a single-hop, multi-hop single-frequency...

Abstract

The invention provides a mesh path selection method and system, and belongs to the field of wireless communication. The method comprises the following steps: judging whether a routing management frameis received or not, and if so, acquiring residual air interfaces of each channel and maximum transmission capability information of each path in each channel; acquiring actual transmission capabilityinformation of each path in each channel according to the remaining air interfaces and the maximum transmission capability information; and selecting the path with the strongest actual transmission capability as an effective path according to the actual transmission capability information. The method has the beneficial effect of solving the problem of inaccurate calculation path transmission capability of a traditional algorithm.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a mesh path selection method. Background technique [0002] In mesh multi-frequency mesh networking, each device is connected in pairs, and there are multiple channels between each device. Whether the data between devices communicates directly or indirectly through other devices depends on the A set of algorithms to determine the specific path. [0003] At present, some algorithms are based on the remaining air interface to evaluate the transmission capacity of the path. For a single hop, the path transmission capacity calculated by using the remaining air interface is accurate; for multiple hops, the transmission capacity of the smallest hop is used to evaluate the entire multi-hop. The transmission capability of multi-hop paths evaluated by this method is not accurate. [0004] The following uses specific numbers to illustrate the inaccuracy of traditional algorithms usi...
