摘　　要：在低密度车流的车载网络(VANET)中,通常只有少数车辆参与路由,就存在通信间隙问题。据此,常采用基于存储-携带-转发(SCF)技术,利用移动车辆桥接两不连通车辆间的通信间隙。为此,针对基于SCF路由,分析了多通信间隙的网络性能。首先为了分析车辆传输半径对端到端传输时延的影响,提出了基于存储携带转发路由的车间通信间隙时延分析模型(SCF-GAM),再量化了关于端到端传输时延的拉氏变换的性能。最后,通过仿真数据验证了SCF-GAM模型。In Vehicular Ad Hoc Network( VANET), there are generally very few communicating vehicles along a routing path in low traffic density areas. Existing schemes based on the Store- Carry- Forward( SCF) technique have utilized a moving vehicle to bridge the communication gap among disconnected vehicles. Therefore, this paper investigates network performance over multiple communi-cation gaps in SCF- based vehicular routing. To investigate the influence of the transmission range on the end- to- end delivery de-lay, this paper develops an analytical model to quantify the performance in term of the Laplace transform of the end- to- end delay.Extensive simulation results are presented to validate the proposed model.
