Abstract: In this manuscript, we present a survey of designs and implementations of
research sensor nodes that rely on FPGAs, either based upon standalone platforms or as
a combination of microcontroller and FPGA. Several current challenges in sensor networks
are distinguished and linked to the features of modern FPGAs. As it turns out, low-power
optimized FPGAs are able to enhance the computation of several types of algorithms in
terms of speed and power consumption in comparison to microcontrollers of commercial
sensor nodes. We show that architectures based on the combination of microcontrollers
and FPGA can play a key role in the future of sensor networks, in fields where processing
capabilities such as strong cryptography, self-testing and data compression, among others,
are paramount. External Link.
