Interference management and control in the cognitive radio network (CRN) is a necessity if
the activities of primary users must be protected from excessive interference resulting from …

In this paper, a novel multi-criteria channel decision model is developed by using the
Enhanced Technique for Order Preference by Similarity to Ideal Solution (E-TOPSIS). The …

The traditional approach for energy detection (ED) consists in the comparison of the energy
received against a fixed detection threshold, estimated according to an expected noise level …

This work presents a spectrum sensing technique based on the entropy of frequency domain
autocorrelation of receiving signal at different cyclic frequencies. The performance of the …

Cooperative spectrum sensing is a process of achieving spatial diversity gain to make global
decision for cognitive radio networks. However, accuracy of global decision effects owing to …

Cooperative sensing is a process of getting spatial diversity gains to improve the
performance of system over impaired cognitive radio networks (CRN). In this paper, an …

This study addresses the reliability of secondary multimedia transmissions under delay
constraints and lossy conditions. In particular, a cognitive radio (CR) infrastructure …

User coexistence in physical layer of OFDM-based cognitive radio is provided by employing
out-of-band (OOB) power suppression methods at the cost of large computational complexity …

It is essential to reduce data latency and guarantee quality of service for modern computer
networks. The emerging networking protocol, Multipath Transmission Control Protocol, can …

This thesis studies the performance of both opportunistic spectrum access (OSA) and
spectrum sharing (SS) cognitive radio networks (CRNs) using cross-layer design (CLD) …
