文档介绍：车载自组织网络中一种连通度感知的可靠数据分发机制摘要摘要车载自组织网络可以通过多跳无线广播实现远距离的数据传输,,文中提出了一种适用于城市场景的可靠的、,建立路口车辆排队长度变化的马尔可夫模型,并基于此模型估算路段间无线网络连通度的实时变化,,用覆盖消除规则改进了贪心广播算法,,与基于传染病的数据分发协议、基于静态节点的自适应数据分发协议相比,文中提出的机制能实现高可靠、:车载自组网络;数据分发;连通度感知;可靠传递OnConnectivity-s(VehicularAd-works),datacanbetransmittedtolong-distancetargetsthroughmulti-hopwirelessbroadcast,,-timetobuildaMarkovmodelofqueuelengthchangeofvehicles,andthenestimatethereal-,-parisonwiththeepidemic-basedprotocolandthestatic-node-:;datadissemination;connectivity-aware;reliabledeliveringOnConnectivity-s,datacanbetransmittedtolong-distancetargetsthroughmulti-hopwirelessbroadcast,,-timetoestablishtheMarkovmodelofqueuelengthchangeofvehicles,workconnectivitybetweenthesections,,-parisonwiththeepidemic-basedprotocolandthestatic-node-:;datadis
