Abstract
LoRa is a low power wide area network (LPWAN) communication that can transmit over long distances under the situation of line of sight, and it is only suitable for transferring small data. Nevertheless, obstacles will severely cause the packet losses and reduce the transmission distance. Hence, we used different spreading factors (SF) to design a hopping network transmission to avoid the obstacle interference and actually achieved the practical long distance communication. In the paper only one-relay for hopping node was tested for feasibility. In addition, to balance the load of the node, every time the picture was transmitted with different cutting ratio. Experimental results show that the one-relay transmission with 1/2 cutting ratio achieves the smallest transmission time. Therefore, this paper verifies the feasibility of hopping image transmission using LoRa.
