Mechanisms for information and knowledge sharing in wireless communication systems

Information and knowledge sharing mechanisms are essential for the efficient operation of cognitive wireless communication systems, complementing learning and decision making and enabling the coordination between various management entities. Information and knowledge sharing mechanisms can be defined as means for transmitting elements of information necessary to manage and realize various operations within future cognitive wireless communications systems. Information may be conveyed from network elements to terminals and vice versa, and may also be exploited for the exchange of information between terminals, so as to increase the accuracy of obtained knowledge. The paper provides an overview of related work and describes several cases of how information and knowledge sharing mechanisms can be exploited in wireless communication systems. A detailed description of the information flow between various entities is provided. An overview of potential implementation options is provided.
