Abstract

The effective in-situ characterization and hazard monitoring in the subsurface are key issues that can be addressed by use of wireless sensor networks. The conventional methods deployed in practice present limitations in acquisition of spatially localized and/or temporally discrete data. The concept of functional signal that takes advantage of the variations of signal strength of the radio waves transmitted among distributed sensor nodes is explored to perform geo-technical characterization in a spatial and temporal continuous fashion in this paper. Simulation and experimental results show that this new approach can provide simple and robust sensing methodology for geo-characterization as well as identifying indiscriminate geo-events by sensing the spatial and temporal evolution of physical conditions in the subsurface.
