A Simulation for a Message Transmission Protocol between LDTS

LDTS와 EIS간 메시지 전송 프로토콜에 대한 시뮬레이션

In this paper a simulation was done to verify performance of a message transmission protocol which interfaces LDTS(Local Data Transmission System) with EIS(Electronic Interlocking System), After a stage of analyzing link specifications between LDTS and EIS, transmission messages and messaging formats, simulation parameters were extracted, applied to the error control schemes such as ARQ, FEC, HARQ, and therefrom throughputs and various performance indices were analyzed Simulation program was constructed with Matlab and Matlab GUI and then converted into a stand-alone c++ program to be used on any non-Matlab environments.
