In this article, we propose a new decentralized hardware-based DBA scheme in TDM-PON. Of particular significance in the proposed scheme is that the bandwidth of the uplink data transmission is dynamically allocated to each ONU without the intervention of the OLT. In this way, software-based DBA processing can be eliminated in the OLT and ONUs, resulting in(More)
In this paper, we propose the power detection (PD)-based TDM-PON architecture, which is implemented for a hardware-based decentralized DBA (dynamic bandwidth allocation) among ONUs, without OLT's intervention to service. The proposed approach is characterized by a simple, fast and cost-effective operation on TDM-PON.
In this paper, we propose the seamless handoff support scheme for broadband real-time services, which is based on the wavelength division multiplexing-passive optical network (WDM-PON) technologies and HMIPv6 in the wireless access network. Firstly, the proposed scheme provides fast and seamless handoff support through the proposed reliable and efficient(More)
