Cognitive radio is a promising technology to meet the requirements of efficient usage of
limited available frequency spectrum for next generation technology and demand for high …

Spectrum sensing is an initial task for the successful operation of cognitive radio networks
(CRN). During cooperative spectrum sensing, malicious secondary user (SU) may report …

One of the most routing problems in Mobile Ad-hoc Network is the node's selfishness. Nodes
are generally selfish and try to maximize their own benefit; hence these nodes refuse to …

In this paper, we design and implement an intelligent gateway for Wireless Body Area
Network (WBAN) that seeks opportunistic access of licensed Primary User (PU) channels …

Cognitive radio offers a flexible and efficient utilization of radio frequency resources by
dynamic spectrum sharing as required in next gen (5G) architecture of wireless …

Traditionally Cognitive Radio Networks (CRNs) have been designed to support real-time
secondary users (SUs) like VoIP. Hidden Markov Model (HMM) based prediction may …

This paper addresses the issue of practical realization of real-time Cognitive Radio (CR)
enabled opportunistic Secondary Users (SUs) through test-bed design and characterization …

Summary Advent of Internet of Things led to an exponential rise in battery‐operated sensors
transmitting small non‐real time (NRT) data regularly. To this end, this work proposes a …

Spectrum scarcity and congestion has motivated new communication paradigm to exploit
the existing wireless spectrum opportunistically. An emerging technology based on …

Conventional distributed power control algorithms in cognitive radio networks are based on
the assumption of perfect channel estimation which may lead to performance degradation in …
