Deploying spectrum sharing machine-to-machine (M2M) communications with the existing wireless networks achieves ubiquitous data transportation among objects and the surrounding environment to benefit our daily life. However, the lack of schemes to completely characterize M2M network topology, to efficiently share radio resource, and to provide quality-of-service (QoS) guarantee regarding end-to-end...
Opportunistic spectrum sharing (OSS) has become an effective method to fully utilize the scarce spectrum resources. In this paper, we propose an OSS scheme with quality-of-service (QoS) support for secondary users (SUs) in cognitive radio networks (CRNs). SUs are classified into the SUs with real-time traffic (RT-SUs) and the SUs with non-real-time traffic (NRT-SUs). The RT-SUs have higher terminated-priority...
Cognitive Radio Networks (CRNs) are emerging as a viable solution for exploiting the available spectrum and solving overcrowding in the operating bands. Several dimensions in the process of identification, management and routing need to be handled to overcome the challenges associated with the management of CRNs. A very important topic in achieving an effective and flexible management solution is...
