| This paper first presents two designs of wireless sensor platforms for real-life applications, Eco and DuraNode. Eco is an ultra-compact, power-efficient and expandable wireless sensor platform. DuraNode is a Wi-Fi based WSN platform, especially designed for civil engineering structural health monitoring. Next, we propose quantitative evaluation tools for wireless sensor networks: Empro and B#. Empro is an environment/energy emulation and evaluation tool and B# is a battery emulation and power profiling instrument. Empro emulates all stimuli to a wireless sensor node including not only all sensory inputs but also power sources and radio signals, allowing the sensor node to run as if it was operating in the actual environment, but with full reproducibility. We also show two efficient energy harvesting platform: Puma and AmbiMax. Puma is a novel technique for matching power sources and power consumers. AmbiMax is an autonomous energy harvesting platform for multi-supply wireless sensor nodes. |
