We will explore the impact of recent technologies on the performance of wireless networked systems that enable the Internet of Things (IoT).  Specifically, we describe advances in wake-up radio technology with semantic addressing capabilities and its usage to obtain very short packet delivery delays and up to five orders of magnitude energy savings, resulting in lifetimes that are decades longer than those obtained with standard energy-conserving methods (e.g., duty cycling). We will then illustrate how combining energy harvesting from different sources (e.g., solar and wind) with wake-up radios enables perennial networked systems with performance similar to that of systems with battery-operated nodes.
