Access point deployment optimization in CBTC data communication system

Research output: Contribution to journalArticlepeer-review


Communication-based train control (CBTC) systems are a new generation of metro signaling system dependent on wireless technology with appropriate access point (AP) deployment. Improved AP deployment can improve the reliability of wireless CBTC systems. This paper proposes a method for optimizing the AP deployment in the data communication system of CBTC. To validate the optimal AP deployment, an integrated simulation environment is used to test the performance of the optimized AP deployments.
