Recently, the use of wireless systems as cellular phones, PHS, Wi-Fi, and WiMAX has been expanding. Meanwhile the resources of wireless radio systems are finite. Therefore, there is concern about exhausting these resources due to their expanded growth. The cognitive radio networks have been proposed to resolve this problem. We previously proposed cognitive(More)
This paper describes a novel approach that guarantees consistency of structure-based configuration models in an evolution process using a knowledge representation based on description logics. We define the term consistency and discuss different notions of consistency that are domain-dependent or configuration-tool specific. Change operations are introduced(More)
