Exploring Caching, Communications, Computing and Security for the Emerging Smart Internet of Things

Feature Topic


It is estimated that more than 50 billion devices will be interconnected by 2020, and the generated data traffic will grow by another 1000 times. The evolution of Internet-of-things (IoT) paradigm not only comes with challenges to the research and industrial communities on finding efficient solutions for massive connectivity, but also poses a profound opportunity to reshape the current IoT architectures by exploring the inherent nature of the huge number of smart devices with caching, communications, computing and security capabilities.

Smart IoT cannot be simply regarded as an upgrade of current IoT by just adding to or replacing sensors/actuators/RFID tags in smart devices. It should be redesigned from the physical layer to the application layer in a bottoms-up way. In the context of smart IoT, communication is essential to guarantee end-to-end connectivity. Together with communications technology, other features, such as caching, computing and security should be fully utilized to complement the current study of IoT. The resulting new structure, by utilizing these inherent features, may have a wider application over current infrastructure-based cellular networks and traditional sensor-based networks by adopting all these features. However, new features also create unexpected problems which can not be directly addressed through the traditional approaches designed for low-rate IoT systems. Thus, how to effectively utilize existing capabilities to address the fundamental challenges in smart IoT remains challenging. Despite the evolution of IoT, some fundamental problems are still open and require immediate investigation.

This Feature Topic (FT) aims at providing timely and comprehensive overviews of the current state-of-the art in terms of fundamental theoretical innovations and technological advances towards exploiting smart caching, communications, computing and cybersecurity for smart IoT networks.
