Although the importance of Disaster Response Networks (DRNs) has been highlighted in
many researches, the requirement of spectrum agility has not been well addressed. In this …

Disaster Recovery Network (DRN) is a very important network to minimize the number of
victims, facilitate the evacuation, and informing the current post-disaster situation. This paper …

Disasters frequently occur across both developed and developing countries, they are
unpredictable in terms of time, place and consequences, victims trapped in disaster area …

In cognitive radio ad hoc networks (CRAHNs), link failures among secondary users (SUs)
primarily result from sudden appearance of primary users (PUs). In tradition, route recovery …

With the swift growth in wireless communication technologies, demand for new radio
spectrum is mounting. Since, radio spectrum is finite, forthcoming technologies may …

In this paper, we propose a cognitive radio based Internet access framework for disaster
response network deployment in challenged environments. The proposed architectural …

Network interoperability and self-organization constitute important communication
requirements in disaster recovery scenarios. Here, the original communication infrastructure …

The cognitive radio (CR) nodes in a cognitive radio network (CRN) do not have license to
use specific spectrum band. Instead, they use the spectrum bands of the licensed primary …

ABSTRACT Cognitive Radio Networks (CRNs) are being studied intensively. The major
motivation for this is the heavily underutilized frequency spectrum. CRN has the capability to …

The new dynamic spectrum environment in cognitive radio networks necessities novel
routing protocols which should be spectrum-aware, self-configured, high-adaptive and …
