A unique challenge for routing in cognitive radio networks is the collaboration between the
route selection and spectrum decision. To solve this problem, in this paper a Spectrum-Tree …

Cognitive radio networks that allow dynamic spectrum access are considered spectrally
more efficient than networks using fixed spectral allocation. These networks are …

Routing in multi-hop cognitive radio net-works (CRN) should consider how to dynamically
switch frequency band for either per flow throughput guarantee or global spectrum …

Cognitive Radio (CR) is an emerging technology to deal with the shortcoming of today's
fixed spectrum management. In cognitive radio networks (CRN), a secondary user can …

In order to improve the connectivity and survivability of Cognitive Radio Networks (CRNs)
under complex and vicious communication environment, we propose a network architecture …

Nodes in Cognitive radio networks can change their communication frequency actively,
which affects networks topology and routing. In this paper, a joint routing and spectrum …

Cognitive Radio Networks (CRNs) is an impressive invention in wireless technology due to
its capacity to resolve spectrum scarcity crisis. It takes benefit of the underutilized licensed …

Cognitive radio networks that allow dynamic spectrum access are considered spectrally
more efficient than networks using fixed spectral allocation. These networks are …

Routing protocols in multi-hop cognitive radio networks (CRNs) can be classified into two
main categories: local and global routing. Local routing protocols aim at decreasing the …

A key challenge in cognitive radio networks (CRNs) is how to adaptively and efficiently
select a route and assign resources along that route according to the surrounding …
