Problems solved by technology

[0006] Poor invulnerability and mobility
The existing communication network relies on pre-deployed network facilities, but in some special occasions, such as the rapid deployment and advancement of troops on the battlefield, rescue after an earthquake or flood, field scientific investigations, remote mountainous areas, accidents, etc., the existing wireless network Extremely difficult to deploy, poor invulnerability, poor mobility, unable to meet application requirements
[0007] Unable to meet the conditions for large-scale self-organized applications
Existing MESH equipment is only suitable for a limited number of nodes, and many problems will arise in large-scale use

Its routing method is also disclosed.

Description

technical field [0001] The invention relates to the technical field of wireless network routing, in particular to a group ad hoc routing method and device. Background technique [0002] Existing wireless local area network equipment and MESH node equipment have the following problems: [0003] Coverage is limited. Existing wireless communication networks rely on pre-deployed network infrastructure, resulting in limited network coverage. In some occasions, although the coverage can be expanded by adding access points, this increases the system cost to a certain extent, and the flexibility and availability are poor; [0004] Unable to make full use of existing network resources. Various existing wireless communication networks have their own frequency ranges, which are incompatible with each other, let alone complement each other, so it is impossible to fully utilize and tap existing network and equipment resources, resulting in great waste; [0005] The service capabiliti...
