Performance evaluation of a LBS system delivering Location-Based Services using wireless local area network

摘要

Location-Based Service (LBS) that requires the knowledge of current position of the user is very promising technology to deliver useful services inside the public facilities. The enormous availability of wireless local area network (WLAN) technology in an increasing number of mobile devices has motivated a lot of researchers to focus on developing LBS system for providing services inside the public hotspots such as university campus, airport, railway station, etc, using WLAN. This paper presents the design and implementation of a LBS system that can provide very useful services inside the public places and evaluates its performance using WLAN technology. Our proposed LBS system provides two services, namely location service and content-mapping service. The performance of our proposed LBS system has been evaluated in terms of service consumption time with respect to the separation distance between the device and the base station (BS) as well as number of clients requesting for service simultaneously in WLAN environment. This paper also demonstrates the variation of throughput achieved by our proposed system in WLAN environment with respect to the distance.
