Executive Summary

Communication-Based Train Control (CBTC) system is an automated control system for railways that ensures the safe operation of rail vehicles using wireless data communications. The train-ground communication system is one of the key subsystem of CBTC. CBTC systems have stringent requirements for wireless communication availability and latency. In this paper, the authors propose a seamless handoff scheme based on Stream Control Transmission Protocol (SCTP) and IEEE 802.11p to provide high link availability for train-ground communication systems in CBTC. Moreover, they propose a handoff decision policy to improve SCTP throughput and achieve seamless handoff in train-ground communications systems. Simulation results illustrate the effectiveness of the proposed scheme.
