| Abstract(in English) | Various estimation methods of crowd density have been studied for safe and comfortable cities. In particular, for installation cost and privacy of people, some methods passively estimate a number of people in a specific space using received signal strength indicator (RSSI) of messages exchanged by wireless sensor nodes deployed in the space. However, they are designed for use in open spaces such as a room or outdoor event space. Therefore, they require the installation of many nodes in these spaces to estimate a congestion area in large indoor environments composed of multiple rooms such as a floor of building. This paper analyzes the impact of people's location in a large indoor environment on RSSI of LPWA (low power wide area) nodes which can perform wide range communication to realize a congestion area estimation by few nodes. |
