Abstract
The rapid growth in computation, smart networking, spectrum agile devices, and hardware miniaturization technologies has led to a major revolution in the wireless sensor
networking landscape in recent times. In particular, the introduction of wireless sensor nodes (WSNs) with cognitionenabled technologies and dynamic spectrum access capabilities can help improve spectrum utilization and optimize the dynamic bandwidth and quality-of-service (QoS)
requirements of application-specific wireless sensor nodes.
Cognition-enabled WSNs require research from multidisciplinary fields including understanding physical systems’
operation; how systems can be networked in a cognitive and
wireless manner; and how they can learn and cooperate with
one another. Automated and intelligent management is one of
the most critical components in making the next generation
smart WSNs more efficient, flexible, resilient, and customizable. Remote monitoring of devices by smart control centers,
introduction of smart self-configuration technologies for
improvement of WSN performance, and smart coordination
of devices are just a few to name that are highly important
topics and are therefore attracting significant interest from
both academia and industry. There has also been recently
a surge in research related to the Internet of Things (IoT)
and, more broadly, the integration of sensor networks over
emerging wireless technologies. In this respect, the unique
combination of the promising wireless paradigm of cognitive
radio networks and the use of sensor networks and IoT
technologies have opened up new avenues for research and
commercialization of such new technologies. The broad
diversity of skills required makes this both a challenging and
an exciting field of study.
