In cognitive radio networks, the new open spectrum operation necessitates novel routing
protocols to exploit the available spectrum opportunistically. But due to the non-interfering …

In this paper, a route selection mechanism for cognitive radio network (CRN) is proposed
where the route construction process selects only those channels which have the maximum …

In this paper, we propose a flexible and resilient communication system using an ad-hoc
cognitive radio network that fully utilizes the available spectrum resources. Two main issues …

Spectrum and energy aware routing is very important in energy-constraint cognitive radio
(CR) networks. On the other hand, it is crucial that CR users efficiently exchange data with …

Cognitive Radio is devised as a wireless communication technology that enables user to
communicate without having a fixed pre assigned radio spectrum. The technology facilitates …

Cognitive radio technology can be used to solve the problems of limited available spectrum
and inefficient spectrum usage by adaptively changing transmission parameters. By utilizing …

Routing is a challenging issue when dealing with the multi-hop cognitive radio networks
(CRNs). The stability of a route is highly influenced by the behavior of the primary user. The …

Cognitive Radio (CR) technology has been introduced to solve the problems of spectrum
underutilization and spectrum scarcity caused by improper spectrum management policies …

Cognitive Radio (CR) emerges as a promising solution to current unbalanced spectrum
utilization. The cognitive ad hoc network can take advantage of dynamic spectrum access …
