Hybrid routing establishment method of dual-mode Mesh network

Abstract

The invention provides a hybrid route establishment method of a dual-mode Mesh network, relates to the technical field of communication, and mainly solves the technical problem of unbalanced loads oftwo paths of a broadband power line carrier channel and a micro-power wireless channel on a dual-mode network node. The method comprises the following steps that a network center node sends a beacon to a network child node to complete networking, and counts neighbor node information of the network child node; the network center node calculates the shortest path to each network child node and issues routing information to the network child nodes; the network child node determines a channel quality grade with the neighbor node according to the SNR value or the RSSI value and a receiving threshold; the channel path weight of the neighbor node is calculated according to the channel quality grade and the weight factor of the message; a channel path weight list of the neighbor nodes is determined, and an optimal transmission channel is determined according to the channel path weight during data transmission. Therefore, the throughput and the channel utilization rate of the network are improved, and the characteristic of coexistence of two medium channels of the dual-mode network is brought into full play.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a method for establishing a hybrid route of a dual-mode Mesh network. Background technique [0002] The local communication network is an important part of the ubiquitous power Internet of Things. The existing local communication network solutions mainly include: narrowband carrier network, broadband power line carrier network, micro power wireless network, narrowband power line carrier and micro power wireless dual mode network, broadband power line carrier and micro power wireless dual mode network. Among them, the broadband power line carrier (HPLC) and micropower wireless (RF) dual-mode network, which integrates the two transmission media and complements each other, has better area coverage and higher information transmission rate. [0003] In a dual-mode network, there are two channels of RF and HPLC at the same time between nodes and nodes. The RF channel or the HP...
