Research on Train-to-Train Communication Resource Allocation for Urban Rail Transport

Abstract As communication technology improves and urban rail system develops, the new CBTC (Communication-Based Train Control) built upon train – train(T2T) has become mainstream of future transit signaling systems. In train-centered system, Train-to-Ground (T2G Train-to-Ground) mode may coexists with T2T mode. To reduce interference ensure reliable transmission information security, a joint channel allocation power control resource distrbution method is proposed, which firstly allocates channels to users by Hungarian algorithm, then make use sparrow search algorithm coordinates user’s transmit power. Obtained simulation results, this suggested strategy not only reduces interferences caused sharing satisfies dependability but also significantly throughput system.
