Adam Cogen '19 will present "Empirical Evaluation of Lower-Power Wide Area Networks (LPWANs) for Internet of Things". His faculty advisor is Professor Farhan Siddiqui. Free lunch and everyone welcome.
The Internet of Things (IoT) is expanding at a rapid pace with various types of “things” acquiring Internet connectivity through wireless technologies. Until recently, IoT connectivity was mostly provided via low-power, short-range technologies such as Bluetooth and Zigbee or high-power, long-range cellular technologies such as LTE. LPWAN is an emerging wireless technology that offers unique characteristics including long-range, low-power consumption, and low- cost. In this research, we explore the feasibility of employing an LPWAN technology called LoRa for building an IoT network. Our empirical evaluation is conducted on a real LPWAN testbed constructed using commercially available hardware components (Arduino boards and shields, Raspberry Pi) and open-source LoRa libraries. The testbed is currently functional on the Dickinson College campus. We investigate the performance of LoRa in terms of network coverage, latency, link reliability, and end-device mobility. We also demonstrate how a LoRa network can be enabled to support end-to-end data encryption and examine the overhead incurred by using 128-bit Advanced Encryption Standard (AES) security keys.
