Conceptual understanding of Cognitive Radio Adhoc Networks

Cognitive Radio Ad-Hoc Network (CRAHNs) is a spectrum responsive system; that is capable of sensing the spectrum white holes; the band which is underutilized by licensed users (primary users) and allocated to the unlicensed users or cognitive users (secondary users); to maximize the licensed spectrum utility, without distressing the priority utilization of the spectrum by license users. This paper provides the conceptual understanding of CRAHNs which discuss the domain objects identified by analyzing the Dynamic Spectrum Management framework (DSMF) in CRAHNs. The paper represents relationship among domain objects using `Domain Object Model of CRAHNs Functions´. The paper aims to contribute towards the analytical study of CRAHNs.
