Abstract
An interplay between mobile devices and static sensor nodes is
envisioned in the near future. This will enable a heterogeneous design
space that can offset the stringent resource and power constraints
encountered in traditional static sensor networks by taking advantage
of the more powerful mobile devices. We present a systematic framework
for end-to-end query processing, using a two-layer architecture that
consists of mobile devices at the "upper layer" and static sensor
nodes at the "lower layer." The framework employs a "PULL" query
model that contains staged operations to support query generation,
query routing, query injection, and query result routing. This talk
will discuss the overall approach and challenges/techniques for each
stage of query processing. Emphasis will be placed on energy-efficient
query injection and query result routing with location-ignorant sensor
nodes.
This work is joint research with Shourui Tian, a PhD student at UIC.
