A new analytical model for multi-hop cognitive radio networks.

  The cognitive radio (CR) is an emerging technique
for increasing the utilisation of communication resources by
allowing the unlicensed users to employ the under-utilised
spectrum. In this paper, a new analytical performance model is
developed to evaluate the QoS of multi-hop CR networks. After
validating its accuracy through extensive simulation experiments,
the analytical model is adopted as a cost-effective tool to
investigate the effects of the primary users’ activities on the
network performance. Moreover, the model can be used to study
the strategy of employing under-utilised spectra so as to maximise
the overall resource utilisation and network performance.
