Abstract
Cognitive Radio Networks have been
proposed to solve the problem of overcrowded
unlicensed spectrum by using the cognitive ability
built in software radios to utilise the underutilised
licensed channel when the licensed users are not using
it. Successful results from the research community
have led to its application to wireless technologies like
Ad Hoc networks due to their extensive advantages.
Cognitive Radio Ad Hoc networks are a novel
technology that will provide a solution to many
communication challenges. This paper investigates
the end-to-end performance modelling of a link using
quality of service parameters; delay vs. link capacity
while considering the factors of spectrum
management and node mobility of two nodes in
tandem representing a hop in Cognitive Radio Ad
Hoc networks. We modelled spectrum management
and node mobility using the pre-emptive resume
priority M/G/1 queuing model and the gated node
model respectively. We considered delay aware
routing schemes; shortest queue and random
probability routing and compared them with the
analytical link-capacity for analysis. The study shows
that already existing mathematical models can be
used as close approximations to analyse the queuing
models proposed for Cognitive Radio Ad Hoc
Networks.
