| Research Abstract |
The objectives of this research are to establish the system architecture that measures member persons' positioning in a large building and its information exchange among members. ZigBee mesh network is utilized for both an indoor positioning and information exchange. As for an indoor positioning method, the triangulation method, the scene analysis and the center of radio gravity have been examined by experiments and ray trace simulations. Next, a network topology and positioning information processing methods have been studied. Furthermore, a performance improvement for a multi-hop WLAN and sensor information exchange using smartphone ad-hoc network have been proposed.
