Abstract
Floating car data (FCD) application is an urban sensing application, which collects the status (position, velocity and heading) of vehicles to feed a traffic management server and estimate the travel time of vehicles, and can be carried by long term evolution (LTE) or a heterogeneous network composed by LTE and vehicular ad hoc network (VANET). However, this application is characterized by high frequency and small data size, which occupy network resource frequently and may have an impact on other LTE traffic, such as human to human (H2H) traffic, which is characterized by low frequency and big data size. In this paper, we aim to analyze and reduce the impact of FCD traffic on the H2H traffic in a LTE-VANET heterogeneous network. For this purpose, we design a novel FCD transmission scheme and evaluate its impact on H2H traffic, which is represented by the rise of the blocking ratio of the H2H traffic, through a Markovian model. The results of the model show that comparing with other schemes, the novel scheme has a relatively lower impact on the traditional cellular traffic, H2H traffic.
浮动车数据(FCD)应用是一种城市传感应用,通过收集车辆的状态(位置、速度和方向),向交通管理服务器提供信息,并估计车辆的行驶时间,可以通过长期演进(LTE)或由LTE和车辆自组织网络(VANET)组成的异构网络来实现。但该应用具有频率高、数据量小的特点,频繁占用网络资源,可能对其他LTE业务产生影响,如H2H (human to human)业务,其频率低、数据量大。在本文中,我们旨在分析和减少LTE-VANET异构网络中FCD流量对H2H流量的影响。为此,我们设计了一种新的FCD传输方案,并通过马尔可夫模型评估其对H2H流量的影响,其表现为H2H流量阻塞率的上升。模型结果表明,与其他方案相比,新方案对传统蜂窝业务H2H流量的影响相对较小。
