Description
FIT/CorteXlab is a radio testbed composed of 42 software defined radio nodes, among which, NI USRPs and Nutaq’s PicoSDRs. These nodes are enclosed in a shielded and semi-anechoic room, isolated from the outside radio environment which promotes reproducible radio experiments. Operational since 2014, it supports state-of-the-art radio experiments, in diverse areas such as cognitive radio, radio security, deep learning for physical layers, and IoT systems, focus of this work.
IoT communication suffers from increased packet collisions due to the ever expanding number of IoT devices, and the study of new channel access policies promises to reduce energy consumption, latency and errors due to retransmission.
In this work we describe the “Slotted and Synchronized multi-Sources experimental framework for the evaluation of new Channel Access Policies” (S3CAP), a new open-source GNU-Radio framework for FIT/Cortexlab. In S3CAP, a custom access policy sets usable slots for each node to transmit to a base station in a slotted and synchronized time frame. The transmitted signal is then generated using a modular and replaceable GNU Radio physical (PHY) layer. Since its conception S3CAP has been used in several studies, and opens new opportunities in the design, evaluation and comparison of both centralized and decentralized random access strategies for future M2M communications.
