Abstract

We propose an efficient proactive data dissemination approach that allows a mobile sink to effectively gather a representative view of a monitored region covered by n sensor nodes by visiting any m nodes, where m ≪ n. Moreover, the proposed strategy allows the mobile sink to follow any trajectory through the deployment region, thus decoupling the data dissemination management from the mobile sink's trajectory.
