Physical Layer Network Coding
A main distinguishing feature of a wireless network compared with a wired network is its broadcast nature, in which the signal transmitted by a node may reach several other nodes, and a node may receive signals from several other nodes simultaneously. Rather than a blessing, this feature is treated more as an interference-inducing nuisance in most wireless networks today (e.g., IEEE 802.11). Th...
متن کاملPhysical-layer network coding in coherent optical OFDM systems.
We present the first experimental demonstration and characterization of the application of optical physical-layer network coding in coherent optical OFDM systems. It combines two optical OFDM frames to share the same link so as to enhance system throughput, while individual OFDM frames can be recovered with digital signal processing at the destined node.

متن کاملPhysical-layer Network Coding for Cooperative Wireless Networks
As a newly-emerged paradigm in the networking techniques, physical-layer network coding (PNC) [1, 5] takes advantage of the superimposition of the electromagnetic waves, and embraces the interference which was typically deemed as harmful, by performing exclusive-or mapping. Therefore, the spectral efficiency is utilized, which in turn boosts the network throughput. In the classical 2-way relay ...
متن کاملNetwork Function Virtualization in Optical Inter-Datacenter Elastic Optical Networks
We first explain the motivations of studying network function virtualization (NFV) in inter-datacenter elastic optical networks (IDC-EONs). Then, we analyze the challenges for provisioning virtual network function forwarding graphs (vNF-FGs) in IDC-EONs, and give insights on how to customize vNF-FG orchestration and optimize IT and spectrum resource allocations jointly. OCIS codes: (060.1155) A...
