Abstract

This paper presents the link availability probability. We evaluate and compare the link availability probability for routing protocols; Ad hoc On-demand Distance vector (AODV), Dynamic Source Routing (DSR) and Fisheye State Routing (FSR) for different number of connections and node density. A novel contribution of this work is enhancement in existing parameters of routing protocols; AODV, DSR and FSR as MOD-AODV, MOD-DSR and MOD-FSR. From the results, we observe that MOD-DSR and DSR outperform MOD-AODV, AODV, MOD-OLSR and OLSR in terms of Packet Delivery Ratio (PDR), Average End-to End Delay (AE2ED), link availability probability at the cost of high value of Normalized Routing Overhead (NRO).

VANETs中城市场景下路由协议链路可用性概率研究
本文提出了链路可用性概率。我们评估和比较了路由协议的链路可用性概率;针对不同的连接数和节点密度,采用了自组织按需距离矢量(AODV)、动态源路由(DSR)和鱼眼状态路由(FSR)。该工作的一个新贡献是增强了现有路由协议的参数;AODV、DSR和FSR分别为MOD-AODV、MOD-DSR和MOD-FSR。结果表明,MOD-DSR和DSR在包投递率(PDR)、端到端平均延迟(AE2ED)、链路可用性概率方面优于MOD-AODV、AODV、MOD-OLSR和OLSR,但代价是标准化路由开销(NRO)值较高。
