Signal Processing and the Internet of Things [From the Guest Editors]

The notion of the Internet of Things (IoT) has emerged as a last-mile solution for connecting various cyber technologies to our everyday life. It envisions a three-tier architecture where highly distributed and heterogeneous sensor data will be collected through a gateway and made available to the Internet to be readily accessible for a wide range of applications. Today, with ever increasing types of IoT devices as well as the growing demand being placed on the end user, the sensing platform, and the computing and storage infrastructure, more is being asked of engineers, designers, and scientists. Discusses how we can leverage today’s pervasive cloud and network infrastructure to foster more intriguing applications with more demanding signal processing and machine learning techniques.
