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.
