异构无线网络多链路并发传输自动化控制方法

针对异构无线网络,为尽可能地避免数据丢失问题的发生,设计了一种多链路并发传输自动化控制方法。首先,构建一个用于描述多链路质量状态的判决因子,根据因子的权重,明确传输环境中不同因素对网络质量的影响,以此实现对链路并发传输质量信息的统一表征处理;然后,设计多链路传输流量的自适应分配模型;最后,引进时延平滑处理技术,对并发传输数据包实施自动化调度,从而完成并发传输自动化控制。实验结果表明:该方法不仅可以提高传输链路的吞吐量,还可以有效避免链路数据在传输过程丢失,有效提高了多链路并发传输质量与效率。

Traffic Assignment Forecast Model Research in ITS

As an important role in the development of ITS, traffic assignment forecast is always the research focus. Based on the analysis of classic traffic assignment forecast models, an improved traffic assignment forecast model, multi-ways probability and capacity constraint (MPCC) is presented. Using the new traffic as- signment forecast model to forecast the traffic volume will improve the rationality and veracity of traffic as- signment forecast.
