Indexing Location Dependent Data in Broadcast Environment

Wireless Data dissemination is an effective way to disseminate large amount of data to a large mobile user population. Our project, called “DAYS (DAta in Your Space)”, investigates information management issues in wireless space. One of the main objectives of DAYS is to build a system to provide transactional and web services facilities globally. This paper discusses the creation of a location domain and proposes an algorithm for creating location dependent data. A new indexing scheme for accessing Location Dependent Data (LDD) in DAYS has also been presented which not only provides a bound on the access time but also allows significant energy conservation in mobile devices.
