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 ...

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 network controlled indoor cognitive radio systems
Australasian Telecommunication Networks and Applications Conference (ATNAC) 2012, 2012Building structures can shield signals and reduce interference. A considerably large area may be allowed for unlicensed operations on the licensed spectrum if the operations only happen indoors. Interference to outdoor licensed users from the indoor operations can be minimised, if the unlicensed users adjust their transmit power according to their ...

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.

Cognitive Radio Sensor Network With Green Power Beacon
IEEE Sensors Journal, 2017In this paper, we propose a cognitive radio sensor network with green power beacon (PB) to solve spectrum and energy scarcity problems in the resource-limited wireless sensor networks. In the proposed model, a PB node harvests energy from ambient sources and transmits the harvested energy to cognitive sensor node (CSN) through in-band energy ...
