Edge Computing for Internet of Things Based on FPGA

The Internet of things (IoT) is a device that can perform mechanical or electrical interaction to its environment while also transferring data through a network. The exponential rise in IoT implementation starts to affect human-to-human communication recently. Furthermore, it is hard to achieve a secure transmission as the microprocessor-based IoT nodes do not have enough computing power. Edge computing in IoT (edge-IoT) promises low bandwidth and secure transmission. Edge-IoT is the ability of a node to perform high computation before sending its data. Thus, instead of sending raw data, an edge node is sending a post-processed the data with much lower bandwidth. An edge-IoT node also can perform a complex encryption computation before the transmission to secure the data. This paper proposes an edge-IoT using field-programmable gate arrays (FPGA) as an IoT node. The edge-IoT with FPGA can perform secure, parallel data acquisition and low bandwidth data transmission with almost the same cost as the microprocessor-based IoT.
