Problems solved by technology

When the router is equipped with multiple radios, the traditional path finding method can only find one path, but cannot take into account the limitations of external conditions. In the process of finding the path, it cannot find the best path that the user needs
[0006] In general, particle swarm optimization methods and genetic methods do not balance shared cognition and natural selection well

Embodiment Construction

[0042] In order to make the object, technical solution and advantages of the present invention clearer, the solutions and effects of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0043] The invention divides the particle population in the multi-radio frequency and multi-channel wireless Mesh network into two parts, one part uses the particle swarm optimization method to update the path, and the other part performs cross operation on the path, and the two methods are combined to find the best path.

[0044] Such as figure 1 As shown, the specific implementation steps of the hybrid routing method in the invention described a kind of multi-radio multi-channel wireless Mesh network are as follows:

[0045] Step 1: Randomly initialize the particle's position and velocity

[0046] In a multi-radio multi-channel wireless Mesh network, there are M possible paths from the source node to the destination node, and each p...

Abstract

The invention discloses a hybrid routing method for a multi-radio-frequency multi-channel wireless Mesh network. The method is implemented through the scheme that a particle swarm in the multi-radio-frequency multi-channel wireless Mesh network is divided into two parts, the routes of one part are updated through a particle swarm optimizing method, interlace operation is conducted on the routes of the other part, and the optimal route is sought by combining the two methods. According to the method, the selecting problem of the optimal route in the multi-radio-frequency multi-channel wireless Mesh network constrained by service quality is solved, stability between knowledge sharing and natural selecting is improved, and the optimal route is more easily found in a searching space.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a hybrid routing method in a multi-radio multi-channel wireless Mesh network. Background technique [0002] Wireless Mesh network is a new type of public wireless local area network and metropolitan area network structure. It transmits data wirelessly to the wired broadband network, which greatly reduces the high construction cost of the wired network and reduces the complexity of network deployment. Innovative technology for configuration and self-healing properties. [0003] Multi-radio multi-channel wireless Mesh network (MCMR-WMN) is an important organizational form in wireless Mesh networks. In MCMR-WMN, the key technology is to find the best path from the source node to the destination node to meet the quality of service (QoS) requirements. But it is extremely difficult to find a path with guaranteed quality of service and an idle interface to transmit p...
