In this paper, we examine the problem of network management for cognitive radio ad hoc networks. (CRAHNs). A cognitive radio (CR) is an intelligent wireless communications device based on software defined radio that is aware of its environment and can adapt to variations to its inputs. Cognitive radio ad hoc networks are distinguished from other wireless networks by their distributed multi-hop architecture and dynamic spectrum access, which introduce many challenges in managing such networks. Whereas traditional network management systems typically monitor and report certain network parameters for potential operator intervention, the Cognitive Network Management Protocol (CNMP) is proposed to provide a framework to acquire, predict, verify and autonomously act on network information to essentially learn and respond to network behavior to meet Quality of Service commitments and user-specific needs within CRAHNs. In this paper, a literature review is given where we describe the areas of classic network management and how the management of CR ad hoc networks is different from the traditional management areas for wireline/wireless networks. The three basic management architecture types are then outlined and the discussion proceeds to overview several relevant network management protocols. Then the proposed framework of cognitive radio network management is introduced and discussed.
