Overview
SpatialSPE
accepts a continuous query and QoS budgets (expressed as latency and accuracy targets) and employs our spatial-aware sampling method (that we dub as SAOS, which is an integral part ofSpatialSPE
) to select an appropriate sample,- then it computes an approximate answer and serves it to the user incrementally, together with rigorous error bounds.
- We have implemented
