Demo: A High-Performance, Energy-Efficient Node for a Wide Range of WSN Applications
Federico Terraneo, Alberto Leva, William Fornaciari · Virtual Community of Pathological Anatomy (University of Castilla La Mancha) · 2016
We present WandStem, a powerful node for WSN applications, ranging from low-power to high-performance ones. WandStem has a powerful 48MHz 32bit CPU with memory protection; thus, it can run untrusted code, to the advantage of security and dependability. It also provides fast current sensing, supporting Coulomb counting and energy profiling. It encompasses hardware timers for packet transmission and reception timestamping allowing accurate time synchronisation and TDMA communication protocols. The node deepsleep current consumption is around 2.4μA; thus supporting long battery lifetime also in ultra-low power applications
