| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We are currently developing and operating a Regional Protection System in Nagano Prefecture Shiojiri City. In this system, terminals that children have regularly send packets periodically. The packets are then transmitted to a server via multi-hop network which is set up some transponders. Therefore, the position of children can be inferred from that information. In this system, we use ARIB STD-T67 of the specific low power radio as the communications protocol. In certain situations that sent packets from terminals are received by multiple transponders, duplicate packets that are sent by each transponders cause highly-loaded network traffic. We proposed such duplicate packets transmission is suppressed, and then a load of the traffic is reduced. In this presentation, the implementations have been performed to evaluate its effectiveness. | |
