基于D2D的列控系统车车通信资源分配算法
T2T (Train to Train) Communication Resource Allocation Algorithm Based on D2D
摘要
Abstract
To tackle the interference caused by sharing train-ground communication resources in train-to-train communication for train control system based on device-to-device (D2D), a T2T communication resource allocation algorithm is proposed while guaranteeing the communication reliability of T2T and train-ground users.Firstly, the channel assignment model is established using the weighted bipartite graph of graph theory.Then, the IKM (Improved Kuhn-Munkres) algorithm is used to allocate channels for T2T communication users.Finally, the power is adjusted to maximize the total throughput of the system.The simulation results show that the proposed algorithm can solve such interference problem, which not only satisfies the communication requirements of the train control system, but also improves the spectrum utilization.关键词
