Remote reconfiguration of FPGA-based wireless sensor nodes for flexible Internet of Things☆

Recently, sensor nodes in Wireless Sensor Networks (WSNs) have been using Field Programmable Gate Arrays (FPGA) for high-speed, low-power processing and reconfigurability. Reconfigurability enables adaptation of functionality performance to changing requirements. This paper presents an efficient architecture full remote reconfiguration FPGA-based wireless sensors. The novelty the work includes ability wirelessly upload new configuration bitstreams a protocol developed provide access flash memory nodes. Results show that FPGA can be remotely reconfigured 1.35 s bitstream stored memory. proposed scheme uses negligible amount logic does not require dedicated microcontroller or softcore processor. It help develop truly flexible IoT, where FPGAs on thousands reprogrammed uploaded without requiring physical
