QoS performance of next generation optical-wireless converged network and PON cycle length

Optical-wireless convergence is becoming one of the evolutionary technologies to provide quality-of-service (QoS) guaranteed ubiquitous access to end users. In this paper, we analyze the effect of GEPON cycle-length on the QoS performance of the GEPON-LTE converged network, when different resource handling mechanisms are used. The simulation results indicate that the influence of different cycle-lengths on the QoS performance varies depending on different traffic types and the resource handling mechanism used. We show that, this dependency can be reduced by introducing a unified resource handling mechanism which also improves the overall QoS performance of the converged network.
