PBS: A virtual grid architecture for gradient-based active querying in sensor networks

Abstract

Every physical event diffuses its effect geographically, which results in perceivable information gradient within the proximity of the phenomenon. In this paper, we propose a novel framework for on-demand query processing that exploits this diffusion property to form a virtual grid-based querying architecture, probe-before-spray (PBS), for wireless sensor… (More)
