碩士 === 國立成功大學 === 資訊工程學系碩博士班 === 90 === The Internet is growing more and more popular in recent years. With the development of the applications and technologies on the Internet such as World Wide Web, people spend much more time on Internet than before, and thus the Internet becomes one part of the human life. At the same time, the proliferation of mobile computing devices and wireless network technologies brings the mobility for Internet Users. Mobile users can use their mobile devices such as PDA and laptops to enjoy the services on the Internet anytime and anywhere with the help of the wireless network technologies such as IEEE 802.11 wireless LAN and Bluetooth. This environment fosters the demand for location information, because mobile users require the applications and services that adapt and respond to the presence of people in their environment. For example, a mobile user can ask a service to search for restaurants, which are close to his location. These services are called location-dependent services. The location-dependent services rely on the location service to provide the location information. In this thesis, we focus on designing and implementing a location service platform in the large-scale IEEE 802.11 Wireless LAN environment. In the system, we can get the location information of the mobile users from the 802.11 infrastructure network, and manage the location information in distributed servers of the system. Our system provides basic functionality for users to query location information of mobile users roaming in the service area of our system. Furthermore, our system can be integrated with applications on Internet to provide the location-dependent services.
