A middleware framework for communication in cognitive radio networks

Cognitive Radio spectrum decision based on channel usage prediction

“…We also assume that there is a Secondary-Access Point (S-AP) in the network. S-AP can be like a base station or a support node [10]. In addition, each of the N SUs always wants to transmit data to S-AP via an idle channel, as shown in Fig.…”

A Multi-reality Approach to CRN Data Representation

“…The suggested architecture reported in [2] is used to control the fundamental operations in the management of a CRN. To achieve this, a centralized entity called Support Node (SN) was introduced to provide support for the cognitive radio communication of associated CRDs.…”

“…By configuring the transmission parameters of a Cognitive Radio Device (CRD), adaptations can be made to the surrounding environment and exploiting every part of available spectrum [2].…”

“…By implementing a particular Cognitive Radio architecture, as suggested in [2], at every base station and mobile device, operators are presented with an opportunity to increase the resource utilization and reduce so the blockage probability. An important part of the suggested architecture consists of a highly modified and adapted Multi-Dimensional ContentAddressable Network (MD-CAN) [2], which is used for:…”
