There is Mifune fall at Kawakami village in Nara prefecture. The waterfall freezes in winter season, and is popular with visitors. In winter it is difficult to access the waterfall due to snow, so there is a need to have information on whether the waterfall was frozen on the internet. Since the waterfall is in the mountains outside the mobile phone area, it is necessary to construct a wireless network from the waterfall to the mobile phone area in order to respond to this need. We investigated the construction of multi-hop wireless network using LoRa. Since LoRa has a low transmission speed, existing multi-hop routing technology that exchanges Hello messages periodically is not suitable. Therefore, we propose a routing method to judge packet relay on the receiving terminal side on a broadcast basis. As a result of the throughput analysis based on the proposed method, we clarified that JPEG image for judging whether it is frozen can be transmitted in about 30 minutes and got a prospect that it can satisfy the needs. In this paper, we describe the results of basic communication experiment of LoRa, multi-hop routing method for low transmission speed and realization of waterfall monitoring system. |
