Bandwidth partition and allocation for efficient spectrum utilization in cognitive communications

Efficient utilization of spectrum bandwidth using Cognitive Radio to improve throughput in wireless adhoc networks

This paper focuses on efficient utilization of spectrum bandwidth to improve throughput in wireless adhoc networks. As the frequency spectrum is a limited resource for wireless communications and as per the next generation requirements the frequency spectrum becomes a scarce resource, and consequently, its efficient use is of the ultimate importance. To meet with the growing demand, network des...

Efficient spectrum sensing and utilization for cognitive radio

Performance of Cooperative Spectrum Sharing and Dynamic Sensing Strategies for Efficient Spectrum Utilization in Cognitive Radio

Due to crowd in the spectrum, interference protection is guaranteed through policy spectrum licensing. Cognitive radio and mesh network can facilitate spectrum sharing that improves spectral efficiency, provided spectrum policies are in place that supports these forms of sharing. This paper discusses the enhancement of Cognitive Radio which enable all the parameter. Cognitive Radios have been r...

Efficient Utilization of Spectrum in Cognitive Networks by Using Femtocell

In communication networks, cognitive network is a new type of data network that makes use of cutting edge technology from several research areas to solve some problems current networks are faced with. Cognitive MACs are becoming a reality for efficiently utilizing the constrained spectral resources. The spectrum opportunities are volatile and often difficult to predict. In this paper we propose...

Efficient Utilization of Spectrum in Cognitive Radio Networks

-The main function of the cognitive Radio (CR) is to use spectrum efficiently and accurately. In this paper, the main aim is to use the spectrum efficiently, which has been allocated to different organizations or companies by centralizing the spectrum. This centralization spectrum can also be taken from the companies which are not utilizing the spectrum presently.
