   Abstract : There has been intense research in vehicular communication in order to provide reliable low-latency vehicular communication links for developing intelligent transportation system (ITS). As one of the important properties, vehicle-to-vehicle (V2V) communication is learned to be inherently non-stationary due to the high mobility of both transmitter (TX) and receiver (RX). READ MORE

6. 5. Embedded Communication Channel for Node Communication in WDM Networks

   University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Author : Anders Rosén; [2015]
   Keywords : Embedded Communication Channel; NE-to-NE communication; ECC-Driver; Socket programming; Linux kernel;

   Abstract : Optical Transport Network is a set of Optical Network Elements (NE) connected by optical fiber links able to provide support for optical networking using Wavelength-Division Multiplexing (WDM). In order to be able to introduce link-level applications that require NE-to-NE communication in a packet-optical network, an embedded communication channel is needed. READ MORE
