"Indexing Structures for Location-Dependent Data in Mobile
Computing Environments"

By

Miss Baihua Zheng


Abstract

We are entering a unique period in the history of computing and mobile
communications. Computing is expected to be embedded into the environment
around us and become a part of our life.  Location-Dependent Information
Service (LDIS), in which responses to queries from mobile users are
dependent on the user locations, is an important kind of application in
the future. In this proposal, a system model providing LDISs is proposed.
Indexing techniques are employed at the server side to improve the
performance.  Unlike traditional, disk-based spatial databases, indexes
for a wireless environment must be small to save wireless bandwidth and
scanning time, and provide fast access time on wireless channels that can
only be accessed sequentially. Detailed research issues related to
indexing location-dependent data are presented and two new index methods
that meet the above requirements are proposed in the proposal.
