Abstract

The invention discloses a LoRaWAN Internet of things signal relay method. The LoRaWAN Internet of things signal relay method is characterized in that: a LoRaWAN relay device and a relay server are added to achieve the relay forwarding of the signal; the LoRaWAN relay device is responsible for completing the replication and forwarding of the LoRa signal; the relay server is located on the back of the network server and is responsible for the management of the LoRaWAN relay device, the frame parsing and the forwarding function. The terminal data forwarding path is as the follows: the mobile terminal, the LoRaWAN relay device, the LoRa gateway, the network server, the relay server, the network server, and the application server, which perform the data interworking in pairs sequentially. The LoRaWAN Internet of things signal relay method can solve the blind area coverage problem of the LoRaWAN, and realize the signal relay problem of the LoRaWAN based on the MAC layer relay.

Description

technical field [0001] The invention relates to a LoRaWAN Internet of Things signal relay method, which belongs to the technical field of LoRaWAN Internet of Things. Background technique [0002] In the field of wireless communication technology, when the signals of the two communicating parties are too weak to communicate, or there is a coverage blind spot in the communication network, the usual solution is to add a relay node to amplify the signal and expand the coverage. [0003] The relay node generally has two sets of physical transceivers, one is connected to the base station, and the other is connected to the terminal. The intermediate node is responsible for sending the information received by the transceiver on the base station side to the terminal through the transceiver on the terminal side, and receiving the information received by the transceiver on the terminal side. The information is sent to the base station through the transceiver on the base station side. ...
