A Survey on Radio Resource Allocation in Cognitive Radio Sensor Networks
IEEE Communications Surveys and Tutorials, 2015Wireless sensor networks (WSNs) use the unlicensed industrial, scientific, and medical (ISM) band for transmissions. However, with the increasing usage and demand of these networks, the currently available ISM band does not suffice for their transmissions. This spectrum insufficiency problem has been overcome by incorporating the opportunistic spectrum

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.
