On practical device-to-device wireless communication: A measurement driven study

We present an empirical study for device-to-device single hop wireless communication. We perform realistic indoor and outdoor measurements of WiFi and Bluetooth communication between representative mobile and IoT devices. This measurement paper aims at answering multiple questions: What are the methods and the limitations in D2D wireless communications for multiple IoT devices? What is the impact of distance/obstacles, environment, and device types on TCP and UDP data transfers? We address these questions, and more, by conducting experimental measurements to cover varying performance aspects such as effective throughput, packet loss ratio, received signal strength (RSSI), and end-to-end delay. Our study presents insights and awareness of the true communication performance of different IoT devices and wireless communication technologies.
