在智慧道路系统(iRoad)中,为了提供服务质量(Qo S)、提高吞吐量,提出了一个面向智慧道路无线网络的动态链路调度(DLS)准入控制模型。通过介绍一种全新的准入控制模型,基于带宽和延迟等相关参数来集成一个动态链路调度方案,该方案满足了信号与加干扰噪声比(SINR)。对数据包采用了竞争信道准入和动态时分多址(DTDMA)的分割,且根据网络的流量和条件建立了无冲突传输。通过模拟实验,证明了模型提高了网络吞吐量,建立了无碰撞传输,以及在满足延迟和带宽方面实现了资源高利用率。
In the intelligent road system( iRoad),in order to provide quality of service( Qo S) and improve throughout,this paper proposed an admission control model of dynamic link scheduling( DLS) based on intelligent road in wireless networks.Through the introduction of a new admission control model,it integrated a dynamic link scheduling scheme based on parameters such as bandwidth and delay. The scheme respected the signal-to-interference-plus-noise ratio( SINR),contended channel access and applied a dynamic time division multiple access( DTDMA) for data packets. In terms of flow and network conditions,it established collision-free transmissions. Through simulating,in terms of delay and bandwidth it demonstrates that the model achieves high resource utilization by improving throughout,establishing collision-free transmission.
