Cognitive radio networks (CRNs) are expected to improve spectrum utilization significantly by allowing secondary users (SUs) to opportunistically access licensed spectrum without affecting the normal communications of primary users (PUs). In a CRN scenario consisting of multiple heterogeneously integrated CRNs, the SUs with multiple interfaces may have to conduct network and spectrum selection for...
In future network, various heterogeneous cognitive radio networks (CRNs) are expected to coexist in the same geographical area to suport Quality of Service (QoS) requirements of both primary users (PUs) and secondary users (SUs). In this system, the SUs with multiple interfaces may select the optimal network for accessing or handing off. Although the problem of network selection and user handoff has...
