Abstract 

Hardware advances will allow us to embed small
devices into everyday objects such as toasters and coffee mugs,
thus naturally form a wireless object network that connects the
object with each other. This paper presents Snoogle, a search
engine for such a network. Snoogle uses information retrieval
techniques to index information and process user queries, and
compression schemes such as Bloom filters to reduce communication
overhead. Snoogle also considers security and privacy
protections for sensitive data. We have implemented the system
prototype on off-the-shelf sensor motes, and conducted extensive
experiments to evaluate the system performance.
