Industrial safety applications using wireless sensor networks (WSN) require fast transmission of still images to identify urgent situation in the target field. However, it is quite challenging to transmit a large number of image packets reliably and quickly through wireless multihop. Thus, the current approaches employ slot scheduling and pipelined transmission, but suffer from many control messages. The proposed protocol exploits LoRa networks for reliable and fast image transmission on WSNs so that it can remove most of control messages related to topology management, slot scheduling, time synchronization, and retransmission. According to experimental results, the proposed protocol improves image transmission delay by 25% compared to the recent pipelined protocol by transmitting one image of 100 × 80 pixels in about 0.3 seconds, and also achieves an image transfer rate of 100% under 1 image packet loss tolerance at an 8-hop distance.
