Embodiment Construction

[0033] The present invention will be further described below with reference to specific embodiments.

[0034] The present invention is a method for creating a Mesh (wireless mesh network) network multi-path route. In a Mesh network, especially a MESH network of inter-frequency networking, the multiple path routes created by the present invention can reuse the bandwidth of each single path. Provide network users with higher bandwidth, reliable and guaranteed data transmission.

[0035] In a Mesh network, the network topology and the quality of wireless links change rapidly, and service connections are interrupted in single-path routing due to the interruption of the path. In addition, the maximum bandwidth of single-path routing is determined by a single path, which does not give full play to the actual capacity of the network. Therefore, providing multi-path routing methods is an effective means to solve such problems. For multi-path routing protocols, it is necessary to sol...

Abstract

The invention relates to a communication method of a multi-path router for a wireless MESH network, which comprises the following steps: the discovery of the multi-path router; the multi-path selection of a target node; the flow distribution of a source node; and the maintenance strategy of a routing table. Compared with the prior art, the method has the advantages that when a user needs routing, the router is triggered to establish a plurality of paths which meet the needs; and a plurality of paths work together, thereby providing business transmission for the user, ensuring the business continuity, and improving the network robustness.

Description

technical field [0001] The present invention relates to the creation of multi-path routing for wireless MESH network and a method for transmitting data through multi-path routing, in particular to a communication method for multi-path routing of wireless MESH network. Background technique [0002] At present, the routing protocols in wireless Mesh networks mainly include proactive routing and reactive routing. Proactive routing such as optimal link state routing protocol OLSR (RFC3626), topology distribution routing protocol based on reverse path forwarding TBRPF (RFC3684 ), etc.; reaction formulas such as Aodv (RFC3561), DSR (RFC4728), etc. However, the above protocols are all single-path routing, that is, a reachable path is maintained between the source and destination nodes, which can be used in wired networks with basically no mobility requirements. It works well, but for a wireless Mesh network with strong mobility, if the end user moves or the quality of the wireless ...
