| Abstract(in English) | With the fast- and wide-spread of IoT and M2M communications services, low power wide area networks (LPWANs) have attracted attention. Periodic traffic dominates the network in environmental monitoring applications because sensors transmit specific environmental information such as temperature and humidity. Since LPWAN adopts a simple asynchronous random access protocol such as the ALOHA protocol, multiple nodes may transmit data packets simultaneously on the same frequency channel at the same time, resulting in packet collisions. Furthermore, continuous packet collisions occur between specific nodes having the same packet generation period due to periodic packet transmissions. This paper proposes a centralized resource allocation scheme suitable for periodic traffic to avoid such continuous packet collision. The computer simulation results show that the proposed scheme can improve the average packet delivery ratio (PDR) by 25% compared to the pure ALOHA protocol. |
