“Methods for Massive, Reliable, and Timely Access for Wireless Internet of Things (IoT)”

Despite the enormous advances in wireless communication technologies over the past decades, providing efficient wireless connectivity to the Internet of Things (IoT) remains a central challenge towards in future generations of wireless networks. Part of the reason for this can be attributed to the diverse set of requirements and characteristics of IoT applications, which are fundamentally different from the broadband applications that have driven the development of current wireless technologies. As a result, supporting IoT requires new methods and protocols that are designed specifically for IoT.

This thesis puts forth a number of methods for providing connectivity for IoT. The methods are designed to address and take advantage of IoT applications with heterogeneous requirements and of correlation between IoT devices. Furthermore, a subset of the methods also assess whether statistical learning and feedback can be used to further enhance the performance. The proposed methods are centered around URLLC, the ability to support a massive number of devices, and applications in which the destination needs to have a timely overview of processes observed by IoT devices. The results demonstrate that although designing connectivity solutions for the heterogeneous characteristics of IoT is challenging, taking into account the specific characteristics can lead to significant efficiency gains compared to providing generic connectivity services.
