Abstract:

The Internet is going mobile, and indications are that on a global scale, the mobile Internet will be "bigger" than the conventional Internet. This talk describes the motivation, status, and goals of an
ongoing research project and evolving system, called Streamspin, that supports data management aspects of mobile Internet services. Streamspin aims to power sites that enable users to create and share geo-social services, and that are capable of delivering services to millions of concurrent users. The talk covers two fundamental services. The first supports the tracking of the continuously changing positions of populations of mobile-service users. The second extends the context of a user to include not only the user's current location, but also the user's (anticipated) destination and route towards that destination.  If time permits, the talk will also cover issues to do with privacy.
