Evolution of Radio Resource Management: A Case for Cognitive Resource Manager with VPI

The cognitive radio and cognitive wireless networks paradigms are interesting candidates for the next generation self-organizing and self-reconfigurable wireless networks. In this paper we argue that the concept of cognitive resource manager as an evolution of the classical radio resource manager in the cellular networks is a promising concept to enable dynamic and distributed cross-layer in the future cognitive wireless networks. We further elaborate on the fundamental and implementation challenges which need to be solved to make the cognitive networks reality. Especially we point out the value of perfect information (VPI) should be taken in account in the real implementations. We also describe shortly, how different APIs need to support information reliability estimation.
