基于室内位置信息的服务推送系统的设计与实现

Based on the indoor mobile nodes positioning technique in the Wireless Mesh Networks (WMN), we design and implement an indoor location-based service pushing system – Peking University Yan Qiong Mobile Service System in this work. The system adopts indoor positioning technique, which can obtain accurate and reliable information of the users’ indoor positions, and thus can provide better services for the users who have indoor activities. Firstly, we describe the indoor positioning algorithms adopted by this system. Then the hardware environment is introduced, including the architecture of the hardware system and the hardware implementation of the positioning system. Afterwards, we describe in details the design and implementation of the pushing system, including the design and implementation of the client, server and database. Finally, we summarize the project, and give an outlook to its improvement and future.
