In this paper we introduce the idea of snapshot queries
for energy efficient data acquisition in sensor networks.
Network nodes generate models of their surrounding environment
that are used for electing, using a localized algorithm,
a small set of representative nodes in the network.
These representative nodes constitute a network snapshot
and can be used to provide quick approximate answers to
user queries while reducing substantially the energy consumption
in the network. We present a detailed experimental
study of our framework and algorithms, varying multiple
parameters like the available memory of the sensor nodes,
their transmission range, the network message loss etc. Depending
on the configuration, snapshot queries provide a
reduction of up to 90% in the number of nodes that need to
participate in a user query.
