Cognitive radios are radios that improve spectrum efficiency and spectrum utilization by operating on unused spectrum channels in their neighborhood. This technology offers a new mechanism for flexible usage of radio spectrum and a broad range of exciting prospects in networking research. This includes the creation of intelligent mobile agent middleware that generates an intelligent framework for deploying applications in cognitive radio networks. In this paper we propose an intelligent mobile agent model for resource and network management in a cognitive radio network, based on the injection of mobile agents into the network that can migrate or clone, following specific rules and performing specific tasks. This model discusses strategies or methods for spectrum decision, spectrum mobility, spectrum sharing, agent mobility and agent cloning.
