| Abstract(in English) | Low power wide area (LPWA) technology that realizes low power consumption and wide area communication is rapidly spreading. LoRa and SIGFOX are patented standards. They use the ALOHA protocol as the MAC layer protocol, and therefore, as the number of nodes increases, more data packets collide with each other. In this report, we propose a transmission scheduling method based on the time-division method. In the proposed method, the communication timing of a node is controlled using a phase oscillator model. Since the bandwidth of the LPWA network is very limited, it is necessary to avoid an increase in control overhead. Also, in order to achieve power saving, nodes are assumed to communicate only with the base station, and it is necessary to avoid communication between them. In our proposed method, each nodes updates its own phase oscillator autonomously and achieves an anti-phase synchronization where the phases of all nodes are placed at regular intervals. In this manner, when the anti-phase synchronization state is realized for each base station, the phase interval indicates the load of the base station, which can be used for load balancing. Computer simulation showed that our method can realize the anti-phase synchronization. |
