The Internet of Things (IoT) and wireless generations have been evolving
simultaneously for the past few decades. Built upon wireless communication and
sensing technologies, IoT networks are usually evaluated based on metrics that
measure the device ability to sense information and effectively share it with
the network, which makes Integrated Sensing and Communication (ISAC) a pivotal
candidate for the sixth-generation (6G) IoT standards. This paper reveals
several innovative aspects of ISAC from an IoT perspective in 6G, empowering
various modern IoT use cases and key technology enablers. Moreover, we address
the challenges and future potential of ISAC-enabled IoT, including synergies
with Reconfigurable Intelligent Surfaces (RIS), Artificial Intelligence (AI),
and key updates of ISAC-IoT in 6G standardization. Furthermore, several
evolutionary concepts are introduced to open future research in 6G ISAC-IoT,
including the interplay with Non-Terrestrial Networks (NTN) and Orthogonal
Time-Frequency Space (OTFS) modulation.Comment: 7 pages, 6 figure
