Influence of uplink limitation and broadcast traffic on power efficiency in long-reach optical access network
نویسندگان
چکیده
Different optical access technologies are studied with respect to their power efficiency. Considered networks provide long-reach optical access. A network model that includes various network and energy related parameters has been developed. The influence of uplink capacity limitation and the amount of broadcast downstream traffic on power efficiency is evaluated within the network model. Long-reach passive optical networks provide the best power efficiency.

Decoupling the uplink and downlink user association improves the throughput of heterogeneous networks (HetNets) and balances the traffic load of macro- and small- base stations. Recently, fiber-wireless HetNets (FiWi-HetNets) have been considered as viable solutions for access networks. To improve the accuracy of user association and resource allocation algorithms in FiWi-HetNets, the capacity ...

To increase the number of subscribers in passive optical networks (PON), various multiple access schemes like time division multiple access (TDMA), frequency division multiple access (FDMA) and its special form orthogonal FDMA (OFDMA) can be used [1]. OFDMA is spectrally efficient and allows adaption to the channel and traffic demand by flexible bitand power-loading. The uplink (UL) direction i...
