Abstract
We demonstrate an analytical model for calculating the saturation throughput
performance of a medium transparent medium access control (MAC) protocol in
60 GHz radio-over-fiber (RoF) networks. The proposed model incorporates effectively
the medium transparent MAC mechanism, assuming a finite number of terminals
and ideal channel conditions. It takes into account contention both at the
optical and wireless layer, ensuring seamless and dynamic capacity allocation
over both transmission media. This model enables extensive saturation throughput
performance analysis for the medium transparent MAC and has been applied to
60 GHz RoF network scenarios considering variable numbers of available optical
wavelengths, wireless nodes and serving antenna elements and for two different
data rate values, namely 155 Mbps and 1 Gbps. Comparison between the model-based
throughput results and respective simulation-based outcomes reveals that our
model is extremely accurate in predicting the system throughput. Moreover,
it confirms that the proposed medium transparent MAC protocol can effectively
operate in high-speed 60 GHz RoF LAN environments.
