Abstract :
Location based services (LBS) are very abundant in our society, which focus on providing users navigation information to make the travel more convenient. With the rapid development of evolving mobile technologies (3G, Wi-Fi, and IPv6), large amounts of data (infotainment, et al.) transmission comes true, which makes the sole navigation information seems tedious. Ubiquitous Computing emphasizes the integration of computing and the environment, while the computer itself disappears from people´s attention. In the ubiquitous computing model, people can access or even process information at any time or any place. In this paper, we propose a new kind of distributed location based service framework of ubiquitous computing. In our service, we can get various kinds of latest information (infotainment), extract their locations by location aware technology considering that there must be a related location in the information. The location-aware information is provided to users whenever they want. All the information sent to users has been filtered according to users´ current locations and locations of the information. User can customize the categories of information to make sure he can get any preferred information but not only the navigation related ones, which makes users´ travel more convenient and pleasant. A comprehensive experiment using real data has been conducted to demonstrate our service framework.
