在车载自组网中,介质访问控制协议(MAC)的转发效率直接影响了数据消息的多跳广播传输性能。 |
In vehicular ad hoc networks (VANET), the medium access control (MAC) protocol was of crucial importance toprovide time-critical multihop broadcast. |

现有方法通常在每跳覆盖范围内选择最远节点来承担转发任务,通过降低转发次数实现快速多跳广播覆盖。 |
Contemporary multihop broadcast protocols in VANET usually choose the farthestnode in broadcast range as the forwarder to reduce the number of forwarding hops. |

然而,通过仿真实验和模型分析,当车辆密度变大时,现有方法导致信道竞争的接入延时剧增。 |
However, it was demonstrated that thefarthest forwarder may experience long contention delay in case of high vehicle density. |

因此,提出了一种基于 IEEE802.11p 协议的多跳广播协议 VDF,根据车辆密度自适应地选择转发节点。 |
An IEEE 802.11p-based multihopbroadcast protocol vehicle density based forwarding (VDF) was proposed, which adaptively chose the forwarder accordingto the vehicle density. |

事故预警和在线游戏 2 种典型应用仿真实验结果表明 VDF 降低了全网广播消息的覆盖延时,同时取得了信道冲突程度和多跳覆盖速度的合理折中。 |
The evaluation results in safety warning and online game applications show that, VDF could shortenbroadcast delay by achieving the proper trade-off between the contention delay and coverage speed. |

针对无线云计算的业务特点,基于软件定义无线网络(SDWN, software-defined wireless network),提出了一种新的能适配云业务特点的 LTE 上行调度方案, |
A LTE uplink scheduling scheme matching the features of wireless cloud services was proposed for the SDWN(software-defined wireless network). |

该方案首先将资源分配问题归纳成二进制整数规划问题进行求解,然后利用动态规划计算出每个调度时隙内云业务的最佳发送速率, |
The scheme first solved the resource allocation problem by using the binary integerprogramming method, and then calculated the optimal transmission rate of cloud services in each time slot using the me-thod of dynamic programming, |

最后通过 SDWN 框架下的 QoS 控制方法动态调节云业务的发送速率,使云业务的发送速率与当前信道条件成正比, |
finally adjusted the transmission rate of cloud services proportional to the current channelstatus using QoS control method in the framework of SDWN. |

从而在保障多业务速率需求的同时,满足云业务能量消耗最小的需求, |
The proposed scheme minimizes the energy consumptionof cloud services while ensuring the transmission rate demand of multiple services. |
