다국어 초록 (Multilingual Abstract)

PLC(Power Line Communication) is communication method that send communication signals in the power line for the purpose of transmitting power. PLC is in the limelight as the emerging technology for constructing ubiquitous network in the new generation because power lines was widespread. Especially, The MV(Medium Voltage) PLC comes to the forefront as new communication source and system for value added of power industries such as AMR(Automation Meter Reading), AMI(Advanced Metering Infrastructure) and High Speed Internet Access as 'Last Mile Solution'. However, The power line communication has many problems, such as interference, variable attenuation, impedance noise levels and signal distortion, etc. One of the serious problems are co-existence issues between power line communication devices. In this Paper, We have designed and implemented simulation for IEEE P1901 CXP standard to solve co-existence issues between power line communication devices. IEEE P1901 standard have 2 physical layer(standard OFDM PHY and wavelet OFDM PHY) and co-existence protocol(CXP). therefore , we analyzed structure of IEEE P1901 CXP and we have developed a simulator. Nodes of NS2-based CXP Simulator have been developed using the mobile node that is provided in NS2. Nodes of NS2-based CXP Simulator is comprised of standard wireless PHY and CXP protocol. In this Paper, By modifying NS2-based wireless channel module, We simulate PLC channel. and We are simulate 4 different CXP modes (No Access Mode, FDM Mode, TDM Mode, No In-Home Mode) that provided IEEE P1901 specification. We implement 4 CXP modes using the simulator and communication performance of each mode was analyzed by simulating each mode. As a result of simulation, We had confirmed possibility of CXP Network as Access Network of AMI. However, The more system complex, communication performance can be seen to decrease rapidly. therefore, the specification in order to be commercially seems to require some modification.
In the future, using the simulator is expected to reduce time to market of PLC devices.
