Despite being one of the most important resources of mobile information systems, the radio frequency spectrum has usually been sparsely exploited as a result of the static spectrum allocation policies traditionally enforced by spectrum regulators. This situation has recently led to the development of novel smart technologies to improve the efficiency of spectrum utilization. Relying on the principles of dynamic spectrum access and sharing and addressing all layers of the communication protocol stack, smart spectrum technologies enable the coexistence of multiple mobile wireless systems within the same spectrum band and therefore offer the potential for a smarter and more efficient exploitation of the radio spectrum in a wide range of mobile scenarios (e.g., TV white spaces, mobile communications, satellite communications, and public safety systems). The research community is working to overcome many of the technical challenges posed by the development of smart spectrum technologies.

We invite submissions of original research articles as well as review articles on both theoretical and practical aspects of smart spectrum systems. Recent results on dynamic smart spectrum sharing technologies in wireless and mobile information systems are solicited. Smart spectrum techniques and their applications in emerging wireless and mobile information systems such as TV white spaces, mobile communication systems (licensed/authorized spectrum access), cognitive satellite communications, cognitive Internet of Things, and other practical application scenarios are particularly welcome.

Potential topics include, but are not limited to:

• Cognitive mobile information systems
• Smart spectrum technologies for TV white spaces
• Licensed Shared Access (LSA) and Authorized Shared Access (ASA)
• Spectrum measurement techniques and statistical models
• Spectrum sensing and sensor networks for smart spectrum systems
• MAC protocols for smart spectrum coexistence and sharing
• Spectrum and radio resource management in smart spectrum systems
• Delay-sensitive and multimedia communications in smart spectrum systems
• Energy efficiency and energy harvesting in smart spectrum systems
• Cross-layer optimization in smart spectrum systems
• Security and privacy in smart spectrum systems
• Deployment strategies for smart spectrum systems
• Spectrum regulation and standardization
