A framework for cognitive radio wireless sensor networks
2012 IEEE Symposium on Computers and Communications (ISCC), 2012The growth of mobile computing has increased the demand for wireless communication, causing a higher demand for the wireless medium as well as spectrum pollution. Smart radios, also called cognitive radios, monitor the network to identify the best available channel, in order to avoid interference. This paper proposes a framework for the development and

Cognitive Radio Based Wireless Sensor Networks
2008 Proceedings of 17th International Conference on Computer Communications and Networks, 2008In recent years, we have seen tremendous growth in the applications of wireless sensor networks (WSNs) operating in unlicensed spectrum bands. However, there is evidence that existing unlicensed spectrum is becoming overcrowded. On the other hand, with recent advances in cognitive radio (CR) technology, it is possible to apply the dynamic spectrum ...

Cognitive Radio Sensor Networks
Proceedings of the International Conference on Intelligent Information Processing, Security and Advanced Communication, 2015Wireless Sensor Networks (WSNs) are a class of technology represented with a set of sensor nodes. The main objective of these nodes is to collect data and monitor an environment's events. The basic tasks a node can handle are sensing data (humidity, temperature, fire, etc.), transmitting over short distances, and performing limited data processing ...

Quality of Service Performance of a Cognitive Radio Sensor Network
2010 IEEE International Conference on Communications, 2010Traditional wireless sensor networks (WSNs) working in the license-free spectrum suffer from uncontrolled interference as the license-free spectrum becomes increasingly crowded. Designing a WSN based on cognitive radios can be promising in the near future as the quality of service requirement for data transmissions increases.

Throughput optimisation in sensor network-aided cognitive radio
International Journal of Sensor Networks, 2013One of the biggest challenges in cognitive radio CR network is to maximise the throughput of the secondary user while keeping the interference to the primary under the interference threshold. Efficient spectrum sensing along with transmit power control can achieve this conflicting goal.

Performance of a Sensor Network Aided Cognitive Radio system
2011 IEEE 22nd International Symposium on Personal, Indoor and Mobile Radio Communications, 2011A 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, 2016Cooperative 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
2014Wireless 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), 2014In 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.
