Performance of a Sensor Network Aided Cognitive Radio system

2011 IEEE 22nd International Symposium on Personal, Indoor and Mobile Radio Communications, 2011
A Sensor Network Aided Cognitive Radio Network uses the concept of a wireless sensor network that assists a cognitive radio network by providing information about the current primary spectrum occupancy. In this paper we study the performance of the cognitive network for various cell sizes and transmit power levels when deployed co-located with a mobile

Transmission Strategy With Cooperative Sensors in Cognitive Radio Networks

IEEE Transactions on Vehicular Technology, 2016
Cooperative spectrum sensing is a technology that allows cooperative sensors to assist cognitive radio (CR) transmitters to intelligently decide their transmission opportunities. Transmissions can only be successful if spectrum is available for both CR transmitters and receivers.

Radio Resource Management in Cognitive Radio Sensor Networks

2014
Wireless Sensor Networks (WSNs) use the unlicensed Industrial, Scientific, and Medical (ISM) band for transmissions. However, with the increasing usage of these networks for diverse applications, the currently available ISM band does not suffice for their transmissions and a new challenge appears before the WSNs' research community.

Sensor placement algorithm for radio environment map construction in cognitive radio networks

2014 IEEE Wireless Communications and Networking Conference (WCNC), 2014
In cognitive radio, current trend is to utilize geolocation database for TV bands. Considering more dynamic bands in terms of primary user activity, however, necessitates the use of Radio Environment Map (REM), which is an advanced knowledge base that stores live multidomain information on the entities in the network and the environment.

Sensing Coverage and Connectivity in Cognitive Radio Sensor Networks

2014
Sensing coverage of a field of interest and connectivity are two very important performance measures in Wireless Sensor Networks (WSNs). Existing design methodologies and protocols for enhanced field sensing coverage and connectivity in WSNs are not directly applicable to Cognitive Radio Sensor Networks (CRSNs) due to their cognitive nature.

Issues in Realization of Cognitive Radio Sensor Networks

International Journal of Control and Automation, 2014
Recently, significant growth in the applications of the wireless sensor networks (WSNs) operating in unlicensed spectrum bands has been made. In the meantime, existing unlicensed bands are becoming congested and overcrowded. On the other hand, Cognitive Radio (CR) technology has been proposed as the key technology for future wireless communication that
