【摘要】：移动Ad Hoc网络的研究已成为网络领域中的重要研究方向,相关路由协议的设计和性能研究工作逐渐成为热点,一个能够对Ad Hoc网络路由协议进行全面性分析的性能评估方法显得越来越重要。Ad Hoc网络路由协议可以使用软件仿真、现场试验、理论分析、经验分析等方法对其进行性能评估和分析。目前,由于现场试验开销高及实验场景部署复杂且不易重现、性能数据不易获取以及理论分析只能对理想条件下的移动Ad Hoc网络场景进行评估分析,而经验分析只适合小型规模的移动Ad Hoc网络场景等原因,软件仿真是对Ad Hoc网络路由协议进行性能评估的主要方法。该方法比较适合于路由协议算法设计方面的研究,而对于网络安全、入侵检测、应用层协议等一些需要实际数据传输与实际算法运行的研究,它并不具有说服力。针对上述情况,本文设计实现了基于有线链路的Ad Hoc网络路由协议性能评估平台(PEPA,Performance Evaluation Platform of Ad Hoc Network Routing Protocol Based on Wired Link),提出了一种基于有线链路的Ad Hoc网络路由协议性能评估方法。通过PEPA平台中的模拟节点搭建移动Ad Hoc网络模拟场景并对相关Ad Hoc网络路由协议进行性能评估分析。这种方法不仅弥补了在软件仿真过程中,未考虑操作系统、系统硬件、系统设计、实际通信环境等敏感因素带来的影响,使得评估结果更接近真实,而且解决了现场试验分析中性能数据不易获取、开销巨大、场景搭建复杂等问题。此外,我们提出了针对降低OLSR协议路由开销的优化方案。本文提出的基于有线链路的Ad Hoc网络路由协议性能评估方法对于高可靠、低延时的新型军用无线Ad Hoc网络的研究具有重大的意义。
[Abstract]:The research of mobile Ad Hoc networks has become an important research direction in the field of network, and the design and performance research of related routing protocols has gradually become a hot topic.A method to evaluate the overall performance of Ad Hoc network routing protocol is becoming more and more important. Ad Hoc network routing protocol can be analyzed by software simulation, field test and theoretical analysis.Empirical analysis and other methods to evaluate its performance and analysis.At present, due to the high cost of field experiments and the complex deployment of experimental scenarios, the performance data are difficult to obtain and the theoretical analysis can only evaluate and analyze the mobile Ad Hoc network scenarios under ideal conditions.The empirical analysis is only suitable for small scale mobile Ad Hoc network scenarios. Software simulation is the main method to evaluate the performance of Ad Hoc routing protocols.This method is more suitable for the research of routing protocol algorithm design, but it is not persuasive for network security, intrusion detection, application layer protocol and so on, which need the actual data transmission and the actual algorithm to run.In view of the above situation, this paper designs and implements the performance Evaluation Platform of Ad Hoc Network Routing Protocol Based on Wired link based on wired link in Ad Hoc network, and proposes a performance evaluation method of routing protocol based on wired link in Ad Hoc network.The simulation scenario of mobile Ad Hoc network is built by simulating nodes in the PEPA platform and the performance evaluation of the related Ad Hoc network routing protocols is carried out.This method not only makes up for the influence of sensitive factors, such as operating system, system hardware, system design and actual communication environment, but also makes the evaluation results more realistic.It also solves the problems of difficult to get performance data, huge cost and complex scene construction in field test analysis.In addition, we propose an optimization scheme to reduce the routing overhead of OLSR protocol.The proposed routing protocol performance evaluation method based on wired link in Ad Hoc networks is of great significance for the research of new military wireless Ad Hoc networks with high reliability and low delay.
