 note = {Due to the increase in the number of IoT devices connected to the internet, 920 MHz frequency bands for wireless communication systems are attracting attention for various IoT applications, e.g., environmental monitoring, smart metering, process monitoring & control. With wireless communication systems on 920 MHz having the features of long distance, low rate and low power consumption, a huge number of IoT devices distributed in wide area can be connected to communication networks. When distributing the same content data to IoT devices such as firmware distribution during operation, improving the efficiency of distribution method becomes an issue. We propose a new content distribution method with fountain coding for IoT devices. For single-hop network, by applying the proposed method, the effective throughput of content distribution was 1.67 to 1.73 times higher than that without erasure code. For multi-hop network, the effective throughput was 1.09 to 1.24 times higher than that without the erasure code., Due to the increase in the number of IoT devices connected to the internet, 920 MHz frequency bands for wireless communication systems are attracting attention for various IoT applications, e.g., environmental monitoring, smart metering, process monitoring & control.
