摘要: Wireless sensors networks enable the chance to investigate with enhanced freedom physical phenomena, aiming increase informative content obtained by measurements. In this work we will focus on a system allowing experimentally measure pressure profiles from sensor nodes deployed NACA0012 aircraft wing model. By exploiting measurements gathered sensors, fluctuations of ±600Pa resolution 4Pa, together results Computational Fluid Dynamics (CFD) models, enables extracting flow profile, thus obtaining information separation and stall phenomenon. measures are delivered an version IEEE802.15.4e, decrease power consumption factor 7. Packet routing, based Routing Protocol for Low-Power Lossy Networks (RPL), has been improved means newly introduced Lifetime Latency Aggregatable Metric (L2AM) leading 18% increased network lifetime.
