as spectrum holes, while protecting the primary
users’ communication. Cognitive radionetworks
have cognitive and reconfigurable properties
and the capability to detect unoccupied
spectrum holes and change frequency for
end-to-end communication. This project is
aiming to design a communication framework
that allows secondary users to communicate
using the licensed spectrum, without
disturbing the primary users’ communication.
To accomplish this, a learning-based network
management approach will be investigated for
network resource management. The proposed
framework will improve spectrum utilization
and prevent against intentional jamming.
The radio spectrum is a finite resource, which is
now in great demand with the proliferation of
new applications and services such as cellular
phones, radio and television broadcast,
Wi-Fi, sensor networks, broadband wireless
Internet access, and so on. Large portions of
the U.S. licensed spectrum are underutilized.
To address the issue of spectrum scarcity,
new communication paradigms have been
proposed.
Cognitive radio has emerged as a promising
technology to improve the overall spectrum
usage by opportunistically allowing secondary
users toutilizeunused licensedbands, referred to
