Performance Evaluation of a Wireless Multi-hop Network using LoRa
Susumu Matsui (OIT) ASN2017-121
Abstract (in Japanese) (See Japanese page) 
(in English) We are studying to disclose a information on whether Mifune fall in Kawakami village, Nara prefecture is frozen or not on the internet. Since the waterfall is in the mountains outside the mobile phone area, we build a wireless network from the waterfall to the mobile phone area with LoRa. In preliminary experiments, it turned out that it was necessary to transmit about 3 hops to transmit data from the waterfall to the mobile phone area, so we have developed a broadcast-based multi-hop routing method. As a result of the throughput analysis based on the proposed method, we have clarified that JPEG image for judging whether it is frozen can be transmitted in about 30 minutes. This time we implemented the routing program based on development method, and measured the throughput. s a result of the performance evaluation, it was confirmed that throughput of about 1/2 to 1/3 of the transmission rate can be achieved in 3 hop environment. As a result, we got a prospect that performance nearly equivalent to the throughput analysis can be achieved.
