"Achievements and the Road Ahead: The First Decade of Cognitive Radio"

The paradigm used by regulatory bodies for spectrum management over the last century has been
"good fences make good neighbors". Regulators have on the one hand attached compulsory and
detailed transmission guidelines to granted licenses, and on the other hand allocated appropriate guardbands between neighboring frequency bands. Although this approach ensures minimum interference,
the growth in the number of wireless applications and technologies has caused frequency allocation
tables to become saturated. Moreover, as various measurement campaigns have shown, most of the
spectrum is underutilized at any given location. Regulators are therefore considering alternative
approaches to spectrum management, such as using market-based mechanisms, introducing
technology-neutral licenses, and allowing secondary spectrum usage.

Cognitive Radio (CR) is a viable means to increase spectrum utilization through leveraging secondary
spectrum access. Upon its conception in 1999, CR was intended to involve RF environment sensing,
model-based reasoning, and learning and acting according to this knowledge in order to improve
communications aspects. However, two major shifts in the focal point of CR are occurring. The first is
a narrower focus on intelligent spectrum utilization, for example through opportunistic/secondary
spectrum access. The other major shift is from autonomous CR operation, which is more suitable for ad
hoc networking scenarios, to cooperative approaches and structured networking architectures, such as
manifested in the IEEE 802.22 standard. This paradigm is generally known as Cognitive Radio
Networking (CRN) or Cognitive Wireless Networking (CWN).

There is tremendous opportunity to improve spectrum efficiency and QoS through shared utilization.
Several IEEE standards groups are working on issues related to spectrum sharing; for instance, IEEE
802.22 is aiming to create Wireless Regional Area Networks (WRANs) based on CR through the
secondary usage of TV bands. In the US, WRANs will opportunistically use the VHF and UHF TV
bands between 52 and 862 MHz. IEEE SCC41 efforts are also developing standards for technologies,
architectures, and facilitators to realize dynamic spectrum access networks. Furthermore, IEEE 802.16h
and IEEE 802.11y are working on interference management and efficient resource allocation in shared
(e.g., unlicensed) bands.

Coupled with the advantages and flexibility of CR systems and technologies, there is an ever-growing
interest around the world in exploiting CR-enabled communications in vehicular and transportation
environments. Through the integration of CR and CRN into vehicles and associated infrastructure,
Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communications, as well as many other
emerging “Killer Applications”, can be expected. CR and CRN, based upon enhanced intelligent
interactions with the transportation system, interactions among vehicles, and even interactions among
radios within vehicles, will help improve radio resource and energy efficiency, road traffic
management, network management, vehicular diagnostics, road traffic awareness in applications such
as route planning, mobile commerce, and much more.

A decade after CR first entered the lexicon of wireless communications, this special issue aims to bring
together a comprehensive view of the major achievements and developments in this field. Through
critical analysis of the state-of-the-art, further aims are to highlight the significant research challenges
that remain in CR and ensuing CRN efforts, to present pioneering solutions to resolve such issues, and
to point the way forward regarding the significant potential for CR and CRN to be employed within
vehicular domains. In line with such objectives, original, unpublished contributions are solicited in
relevant topics, including but not limited to:
