OPTIMIZING BATTERY CONSUMPTION OF REMOTE TERMINAL DEVICES OF WIRELESS LONG-DISTANCE WIDE AREA NETWORK (LoRaWAN)

A long-distance wireless network is paired with repeater terminal equipment to relay the data of the remote terminal equipment to the gateway, so that the service life of a battery of the remote terminal equipment is prolonged. The battery life of the repeater terminal is reduced, so that the battery life of the remote terminal equipment is prolonged. The analysis server selects a pair of terminal devices whose battery power difference is higher than a threshold value, and the transmission energy required from the remote terminal device to the repeater terminal device is less than the transmission energy to the gateway. The energy or path loss is estimated from the geographic location and terrain or obstacles of the terminal device. Redundant pairing of remote terminal devices is deleted by selecting a repeater terminal device that requires the lowest transmission energy. A new configuration is sent to the remote terminal device. A new configuration with a higher spreading factor (SF) may compensate for pairi
