Studio e validazione di modelli di propagazione radio in ambiente urbano per tecniche di localizzazione non cooperativa

La previsione della copertura RF in ambiente urbano è oggi comunemente considerato un problema risolto, con decine di modelli proposti in letteratura che mostrano una buona approssimazione rispetto alle misure. Tra questi, il ray tracing è considerato come uno dei più accurati tra i modelli disponibili. In questo lavoro si dimostra però come sia ancora necessario parecchio lavoro per fare in modo che il ray tracing possa essere effettivamente impiegato per scopi pratici.

Ultra Low Power FPGA-Based Architecture for Wake-up Radio in Wireless Sensor Networks

In this paper the capabilities of ultra low power FPGAs to implement Wake-up Radios (WuR) for ultra low energy Wireless Sensor Networks (WSNs) are analyzed. The main goal is to evaluate the utilization of very low power configurable devices to take advantage of their speed, flexibility and low power consumption instead of the more common approaches based on ASICs or microcontrollers. In this context, energy efficiency is a key aspect, considering that usually the instant power consumption is considered a figure of merit, more than the total energy consumed by the application.
