Problems solved by technology

[0003] However, although the existing MR-MC channel allocation technology can achieve good results, there are almost no channel allocation algorithms specifically designed for power distribution scenarios.
Moreover, most of them are based on single-band networking, which cannot well meet the needs of power dual-band networking.

Abstract

The invention discloses a method for allocating multiple radio frequencies and channels in a wireless self-organizing network with multiple frequency bands, including determining the cluster head nodes in the network; forming a backbone topology network according to the cluster head nodes and gateways; according to the backbone topology network, and each The members in the cluster determined by the cluster head node form the final topology of the network; according to the final topology network, channel allocation is performed on the links of the backbone network and the links in each cluster; during the normal working process of the final topology network, when Fault recovery is carried out after the failure of the cluster head node is detected. Therefore, the multiple radio frequency and channel allocation method of the multi-band power distribution wireless ad hoc network can improve the overall performance of the network, thereby ensuring the service quality of users and improving user experience.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a method for allocating multiple radio frequencies and channels of a wireless self-organizing network with multiple frequency bands. Background technique [0002] At present, the BPTCA channel allocation algorithm is based on a single-band wireless Mesh network. Its core idea is to reduce the power of nodes as much as possible and the degree of unit neighbor nodes as much as possible under the premise of ensuring network connectivity. Then, the topology control and channel allocation algorithm Join together for consideration and analysis. At the same time, the BPTCA algorithm can also automatically repair node failures. [0003] However, although the existing MR-MC channel allocation technology can achieve good results, there are almost no channel allocation algorithms specially designed for power distribution scenarios. Moreover, most of them are based on single-band...
