Abstract: Based on the core idea of sharing, a novel extensible Location Based Service (LBS) named the Location Based Participatory Sensing Service (LBPSS) is proposed. It is designed to solve the current LBS problems, such as the delay of POI (point of interest) update, the difficulty of data collection, the low viscosity of the users and so on. The architecture of the LBPSS system is described in detail and the advantages and characteristics of LBPSS compared to LBS are selectively analyzed. For the implementation of LBPSS, five key technologies like privacy protection, incentive of participation, data validation, mining and visualization, are presented. The users of LBPSS can provide the data based on the location and get the data and services at the same time, achieving the purpose of more diverse data collection and the wide data sharing usage. Finally, integrated with ArcGIS Server and Android platform, the application of LBPSS in air quality monitoring is realized to verify the feasibility and validity of the LBPSS.

摘要： 以共享为核心理念, 探索一种新型的可扩展的 LBS?? 基于位置的参与式感知服务(LBPSS), 用于解决当前LBS系统POI更新缓慢、数据采集困难以及用户黏性小等问题。详细设计了LBPSS系统的架构, 并分析LBPSS相比于LBS的优势及特点。针对LBPSS的具体实现问题, 提出隐私保护、参与激励机制、数据可信验证、数据挖掘和数据可视化五项关键技术。LBPSS用户能够基于位置提供数据同时获取数据及服务, 实现更多类型数据的采集与数据共享利用。最后结合ArcGIS Server和Android平台实现LBPSS在空气质量监控中的应用, 验证LBPSS的可行性和有效性。
