지하철 역사내 WSN 환경구축을 위한 성능 측정 분석

초록

An intelligent surveillance system can be organized various ways and presented a proper configuration according to its purpose and function. It needs a test to measure and analyze system performance considering installation sites of sensor node, sync and interference under the real environment to optimize a WSN system configuration which is the most important part of intelligent surveillance system for urban transit. In this paper, we describe the features of the existing WSNs and analyze the results of the WSN's performance test in the subway stations. We measure and analyze performance of the data transmission of which it is built WSN system using Bluetooth, WLAN, Zigbee sensor node in the Busan station building of Busan subway station line 1 and the Yeonsan subway station line 1,3. We expect that the results can be very helpful to construct intelligent surveillance system and observe the real-time events in subway.
