高动态Ad Hoc路由协议性能分析

Ad Hoc网络是一种没有固定设施的无线移动自组织网络,动态变化的拓扑结构对路由协议的性能有着重要影响。研究了动态源路由(DSR)协议、Ad Hoc按需距离矢量(AODV)路由协议和最优链路状态路由(OLSR)协议3种传统路由协议,利用OPNET软件作为仿真工具,设计了2种不同网络规模条件下空中飞行平台网络拓扑结构背景的高动态仿真方案,通过比较网络时延、归一化网络吞吐量、路由负载和数据传送成功率,分析了它们的性能。仿真结果表明,OLSR协议的综合性能优于其它协议,更适合于节点高速移动且网络拓扑结构频繁变化的Ad hoc网络,并为下一步研究打下基础。

Performance Analysis of High-dynamic Ad Hoc Routing Protocol

Ad Hoc network is a kind of wireless mobile self-organized network without fixed facili- ties. The dynamic topology structure has considerable effect on the performances of routing proto- col. This paper studies three traditional routing protocols：dynamic source routing （DSR） protocol, Ad Hoc on demand distance vector （AODV） routing protocol and optimized link state routing （OLSR） protocol,taking the OPNET software as simulation tool,designs high-dynamic simulation scheme in airborne platform network topology structure background under two different network scale condituons, through comparing network time delay, normalizing network throughput, route load and data delivery ratio, analyzes their performances. The simulation results show that the com- prehensive performances of OLSR protocol transcend others, and OLSR protocol is more suitable for Ad Hoe network whose node moves fast and the network topology structures change frequent- ly, which provides the basis for further research.
