摘要
本文提出了一种基于密度、网络连通性和通信时间的节点分布框架。根据建模框架，我们评估和比较了三种路由协议的性能，即Ad-hoc按需距离矢量(AODV)，动态源路由(DSR)和鱼眼状态路由(FSR)在manet和vanet中使用两种mac层协议802.11和802.11p。我们进一步修改了这些协议，改变了它们的路由信息交换间隔，MOD AODV, MOD DSR和MOD FSR。在NS-2中进行了全面的仿真工作，以比较这些路由协议对节点的不同移动性和可扩展性的影响。为了评估这些协议的效率，将吞吐量、端到端延迟(E2ED)和归一化路由负载(NRL)作为性能参数。经过大量的模拟，我们观察到AODV在manet和vanet中都表现出色。
Analysis and Modeling of Network Connectivity in Routing Protocols for MANETs and VANETs
In this paper, a framework is presented for node distribution with respect to density, network connectivity and communication time. According to modeled framework we evaluate and compare the performance of three routing protocols, Ad-hoc On-demand Distance Vector (AODV), Dynamic Source Routing (DSR) and Fisheye State Routing (FSR) in MANETs and VANETs using two Mac-layer protocols, 802.11 and 802.11p. We have further modified these protocols by changing their routing information exchange intervals, MOD AODV, MOD DSR and MOD FSR. A comprehensive simulation work is performed in NS-2 for the comparison of these routing protocols for varying mobilities and scalabilities of nodes. To evaluate their efficiency, throughput, End-to-End Delay (E2ED) and Normalized Routing Load (NRL) of these protocols are taken into account as performance parameters. After extensive simulations, we observe that AODV outperforms both with MANETs and VANETs.
