Research And Implementation Of Mobile Service Based On Location Aware

Research and application of services based on location has been used widely in people's lives and in various industries, and the most important research, LBS, that mobile services based on location-aware has become a hot rush, and meanwhile, the development of wireless internet and mobile computing make the mobile services based on location-aware develop widely. In short, this service provides users with information services that related to location information.Location-aware computing is a key technology of location service. However, the domestic research and applications of location-aware are still in the initial stage and in terms of portability and scalability are not perfect. This paper launches research of the location-aware computing and researches and analyzes the key technology, such as positioning technology and location algorithm, and presented the system model of location-aware computing based on the research.About the service aware of location service, this paper analyzed and compared the existing service aware technology in the terms of description mechanism, discovery mechanism and so on, and presented the improvement strategies of service aware technology in terms of spontaneity, initiative and so on to adapt the requirements of the mobile services based on location-aware. About the mobile service based on location-aware, this paper used the Slope One algorithm to provide service. And this paper used the group and benchmarking ideas to improve the Slope One algorithm based on the research. So the algorithm in the application of location service is simpler.Finally, the system of mobile service based on location-aware is realized on the basis of the study of the knowledge. This paper designed and realized the mobile service system based on location-aware on the Android platform, and tested the system on the windows platform, and proved the feasibility of the system, and also, proved the feasibility of the research of the mobile service based on location-aware.
