Data management issues in disconnected sensor networks
The possibility of disconnection is one of the fundamental new networking problems presented by sensor networks. The goal of this paper is to address the problem of result collection in periodically disconnected sensor networks, focusing, in particular, on opportunities for in-network processing. Our hypothesis is that, through careful augmentation of the networking layer underneath the declarative query processor, it will be possible to expose information that will make the query processor able to adapt to and handle disconnections.
