Keynote Title: Massive Internet of Things Supporting Industry 4.0
The Internet of Things (IoT) is predicted to contribute 11% to the global economy in 2025 according to some studies leading to the revolution of industry 4.0 for massive services. However, the problem of massive number of connections involving billions of devices are remaining unsolved in practice. In this talk, we try to solve the massive number of connection using the concept of coding theory combined with successive interference cancellation to maximize the success of multiple access mechanism.
Due to the nature of huge number of connecting devices, we prefer random access scheme rather than scheduling, called coded random access (CRA). We found that the proposed CRA multiple access scheme provides highest throughput among the current IoT technologies. The IoT with pure ALOHA achieves 0.18 packet/slot; IoT with slotted ALOHA provides 0.37 packet/slot; IoT with non-slotted carrier sense multiple access with collision avoidance (CSMA/CA) achieves 0.5-0.8 packet/slots; Iot with slotted CSMA/CA reaches 0.8 packet/slot, while IoT with the proposed CRA scheme can achieve 0.9-3.7 packet/slot, which is about 20x compared to the IoT with pure ALOHA scheme. Due to the unpredictable number of future connecting devices, we derive a theoretical network capacity based on the extrinsic information transfer (EXIT) chart analysis to predict the rate and traffic expressing the number of connecting devices.
