Delay Tolerant Delivery of Quality Information in Ad-hoc Networks

We study the delivery of information in ad-hoc networks. We consider information-sources and information-consumers and the in-between network. Information has a certain quality indicator that fades over time. Consumers (applications that process incoming data) can receive and process disseminated information from its generation time until the associated quality reaches the lowest possible level. We adopt optimal stopping theory in order to study the problem of optimally scheduling information consumption. The assumptions of our study include an efficient epidemic information dissemination scheme. We adopt the latter scheme for a combined setting where receiving nodes delay the reporting of information to applications in search for better quality while the overall network optimizes transmissions through the epidemic abstraction.
