Channel bonding/aggregation techniques, which assemble several channels together as
one channel, could be used in cognitive radio networks for the purpose of achieving better …

Cognitive radio (CR) improves spectrum efficiency by allowing secondary users (SUs) to
dynamically exploit the idle spectrum owned by primary users (PUs). This paper studies …

Recently, cognitive radio (CR) has become a key technology for addressing spectrum
scarcity. In CR networks, spectrum access should not interfere the colocate incumbent …

Wireless local area networks (WLANs) are the most popular kind of wireless Internet
connection because of their simplicity of deployment and operation. As a result, the number …

Cognitive radio networks have been recognized as a promising paradigm to address the
spectrum under-utilization problem. To improve spectrum efficiency, many operations such …

Currently, the radio spectrum is statically allocated and divided between licensed and
unlicensed frequencies. Due to this inflexible policy, some frequency bands are growing in …

To improve the utilization of the precious radio spectrum, we propose a channel-hopping
based cognitive radio medium access control (MAC) protocol for synchronized wireless …

Cognitive radio networks (CRNs) have emerged as a critical technique for solving spectrum
shortage problems and enhancing the utilization of licensed channels. To prevent …
