Abstract :
In this paper, we propose a novel MAC protocol adopting time division duplex (TDD) technology, which can extend total subscribers for WDM/Ethernet passive optical network (WE-PON) at the expense of downstream bandwidth. To compensate sacrificed downstream bandwidth, we employ an efficient threshold decision and dynamic bandwidth (DBA) algorithm that maximize protocol performance. For reliable performance validation, it is simulated using OPNET under the various kinds of network parameters. Simulation results show that novel MAC protocol achieves a substantial improvement in queueing delay, queue size and link utilization
