The evolution of future wireless communication systems imposes a strong requirement on the efficiency of spectrum usage, which is expected to be leveraged by interacting and cooperating cognitive radios forming wider cognitive radio systems. Dynamic spectrum access is a potential means to improve spectrum usage. A key step in realizing DSA is to obtain spectral occupancy information provided by spectrum...
This paper presents the types and classes of sensing related information to be exchanged among the entities in cognitive radio systems. The information was extracted by analyzing distributed spectrum sensing use cases and has been checked for the consistence with available sensing techniques and sensors' capability. This paper also introduces IEEE P1900.6 WG recent activities on standardizing the...
This paper introduces recent R&D on distributed spectrum sensing, the use cases for distributed sensing approach and the need of exchanging sensing related information among different devices in a cognitive radio system for dynamic spectrum access. This paper also shows the latest standardization activities on the interface for sensing information exchange between the sensors and their clients.
