Slotted, synchronised and modular framework for the evaluation of channel access policies in dense IoT network using FIT/CorteXlab

Abstract

IoT communications may suffer from extensive collisions when an ALOHA-style transmission policy is used. The study of new decentralized channel access policies promises to reduce energy consumption, latency and errors due to retransmission induced by such collisions. In this paper we describe a Slotted and Synchronized multi-Sources experimental framework for the evaluation of new Channel Access Policies (S3-CAP). Each node transmission to the base station is made in a shared slotted time-frame where a decentralized access policy determines which slot to use. Then, a modular and replaceable physical (PHY) layer is used to create the transmitted signal. The IoT network can be either emulated on a local computer with a simulated channel or deployed in the FIT/CorteXlab testbed where slot synchronisation between all nodes is provided by a clock distribution module. This open-source framework, designed in a GNU Radio environment, opens perspectives to design, evaluate and compare decentralised random access strategies for M2M communications.
