Abstract:
In this paper we propose a distributed meta-index using a
peer-to-peer protocol to allow spatio-temporal queries of moving objects
on a large set of distributed database servers.We present distribution and
fault tolerance strategies of a meta-index that combines partial trace of
object movements with aggregated data about the number of objects in
the database servers. The degrees of distribution and fault tolerance were
compared by using discrete-event simulators with demanding spatiotemporal
workloads. The results show that the distributed meta-index
using Chord provides good performance, scalability and fault tolerance.
