Guest Editorial: Pervasive, Efficient, and Smart Signal Processing for IoT

The Internet of Things (IoT) lies at the core of the unprecedented connected era we are currently speeding towards. Both Academia and the Industry strive to push the limits of technology fueled by vertical applications such as: factory 4.0, eHealth, human-centric and tactile IoT, wearable IoT, smart city/building, digital twin, etc., which will shape our future society and significantly impact both economic and societal aspects. Signal Processing (SP) plays an important role in expanding the number of IoT technologies and capitalizing on their applications. This is due to the sophisticated processing of signals and data gathered and shared by connected things.
