The invention discloses a hybrid mesh network construction method and a data transmission method based on the hybrid mesh network. When constructing a hybrid mesh network, a fusion layer is added between the data link layer and the network layer, and multiple different mesh networks are constructed on the data link layer. The mesh network of the mesh network assigns a new node address for each host node of the mesh network at the fusion layer. When performing data transmission, determine the priority of each mesh network according to the link parameters of each mesh network in the mixed mesh network, determine the target mesh network with the highest priority, and transmit the data message according to the target mesh network to the destination address. Therefore, instead of using a mesh network for data transmission, the mesh network with the highest transmission efficiency is selected for data transmission during data transmission. This reduces the impact of signal interference on the mesh network and improves data transmission efficiency.
Description
technical field [0001] The invention relates to the communication field, in particular to a hybrid mesh network construction method, a data transmission method and a device. Background technique [0002] Mesh (full name in English: Wireless Mesh Network, full name in Chinese: wireless mesh network) network, also known as "multi-hop (multi-hop)" network, it is in WLAN (full name in English: Wireless Local Area Networks, full name in Chinese: wireless A broadband wireless access technology developed on the basis of LAN), but unlike WLAN, the entire Mesh network includes two parts: the access plane and the transmission plane. The access plane is composed of a single Mesh router and multiple mobile terminals, and the mobile terminal accesses the Mesh network through the Mesh router connected to itself. The transmission plane is a multi-hop wireless network formed by the interconnection of multiple Mesh routers. Mesh routers can simultaneously integrate the function of AP (Engli...
