Beschreibung
Zusammenfassung:The paper presents design and implementation of a wireless sensor node suitable for medical applications. As physiological signals are highly redundant, the data compression algorithms (Huffman's coding) are used to save energy and improve the node performance. Design is based on the ARM Cortex M1 processor and implemented in FPGA.
