Design and Implement of Real-Time Hybrid Position Tracking Service System using USN in the Multi-Floor Building

USN various services and interest in continuous as a various applications services based on the USN has emerged. In such USN is the application of these technical elements of the situation with the necessary components are present, and about whether the situation obtaining basic data on the precise location information have been actively investigating. Recent applications that require the services within a few meters into space with the precision of the real-time location tracking techniques presented in the form of short-range communications technology is being used, these real-time location tracking services using technologies interior space of the user s real life environment is available at most two will be subject to multi-story building. For real-time location tracking technology in multi-story building separated from each layer spread on the assumption that the other does not pass the ground floor flat has been conducted for applications in. However, multi-layer structure of the building due to the interference between each layer to track the location of the user is likely to cause errors in dee. In this paper, USN of the communication interface using IEEE 802.15.4 Zigbee area of the RSSI-based detection algorithm and the IEEE 802.15.4a Floor CSSS take advantage of the technology of triangulation-based positioning algorithm is applied to the location of the jeongmeolhan-layer structure of the multi-story building environment to provide real-time location tracking services systems for hybrid real-time location tracking services to design and analyze the results.
