Cognitive Radio Wireless Sensor Networks are emerging technology which provides cognitive capabilities to Wireless Sensor Networks. WSN operates in unlicensed band. Same spectrum band is shared by other wireless devices like Wi-Fi and Bluetooth. Due to this, the unlicensed spectrum is overcrowded which degrades the performance of WSNs. To overcome this issue, Cognitive Radio is integrated with ...

In this paper, resource allocation models for cognitive radio networks (CRN) using game theory are presented. The study includes the concept of cognitive radio (CR) networks, cooperative and non-cooperative game theory, and modeling of strategic interaction process for CR enabled secondary users. The prime objective of the present study is to compare existing game models for CR networks in term...

Cognitive radio sensor network (CRSN) has emerged as a promising solution to address the spectrum-related challenges of wireless sensor networks (WSN). Moreover, cognitive radio (CR) gives us a possibility to maximize the utilization efficiency of limited spectrum resources. In this paper, we propose an intelligent power control scheme to address the communication requirements in cognitive radi...

Cognitive Radio plays a major part in communication technology by resolving the shortage of the spectrum through usage of dynamic spectrum access and artificial intelligence characteristics. The element of spectrum sharing in cognitive radio is a fundamental approach in utilising free channels. Cooperatively communicating cognitive radio devices use the common control channel of the cognitive r...
