Framework for PHY-MAC layers Prototyping in Dense IoT Networks using FIT/CorteXlab Testbed

In this paper we present an Internet-of-Things (IoT) network implementation developed as part of the project “Enhanced Physical Layer for Cellular IoT” (EPHYL), using FIT/CorteXlab radio testbed. The aim of our work is to provide a customizable and open source design for IoT networks prototyping in a massive multi-user, synchronized and reproducible environment thanks to the hardware and software capabilities of the testbed. The massive access feature is managed by emulating several sensors per radio nodes. Two categories of network components are used in our design: a base station unit and a multi-sensor emulator unit. The components are separately hosted in dedicated and remotely accessible radio nodes. Their design features can be illustrated through a live demo, which is also reproducible as it is available for any interested reader.
