高速移动自组网中DSDV与OLSR协议的仿真与分析

Simulation and Analysis of the DSDV and OLSR Protocols in the High Speed Ad Hoc Network

介绍Ad Hoc无线自组网中的特点及表驱动路由和按需路由两类路由协议,分析DSDV和OLSR两种经典路由协议及其工作原理.使用NS2网络仿真软件对以上两种路由协议进行仿真,仿真环境中设置节点为高速移动模式,通过丢包率、端到端平均延迟、延迟抖动和吞吐量4个性能指标,对这两种路由协议的性能进行比较分析.仿真结果表明,OLSR相对于DSDV更适合于高速移动自组网的应用场合.

First the paper introduces the characteristics of Ad Hoc network and the table-driven and on-demand routing protocols, and then mainly analyzes the two kinds of classical routing protocols and their working principles. In order to compare different performances with DSDV and OLSR, the simulation software NS 2 is used.The nodes in the simulation environment are set for high speed mode, and through the four performance indexes including the packet loss rate, average end-to-end delay, delay jitter, and throughput the performances of them cre analyzed. The simulation results indicate that OLSR relative to DSDV is more suitable for the application of high speed mobile Ad Hoc network.
