摘要: Ad hoc路由协议可以使用软件仿真、现场试验分析、理论分析等方法对其进行性能分析和评估。由于现场试验分析开销高及实验环境部署复杂等原因,目前,软件仿真是对ad hoc路由协议进行性能评估的主要方法,但这种方法对于一些需要通过实际应用场景对ad hoc网络进行研究的情况并不具有说服力。本文综合各种方法的优缺点,提出一种基于有线网络的ad hoc路由协议性能评估新方法:通过在应用层、网络层、链路层添加各种数据采集探针来采集性能数据。此外,设计并实现了可视化的数据采集分析平台,可以对采集的性能数据进行图形化的展示及分析评估。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、通信环境等敏感因素带来的影响,使得测试结果更逼近真实,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。最后,通过本文所提出的性能数据采集评估方法对3种典型的ad hoc路由协议进行性能对比分析。

Abstract: Software simulation and in-situ test analysis, theoretical analysis and other methods can be used for performance analysis and evaluation of ad hoc routing protocol. Due to the high cost of in-situ test analysis and the complicated experimental environment deployment, at present, the software simulation is the main method for ad hoc routing protocol performance evaluation, however, this method is not convincing for the study of ad hoc networks through practical application scenarios. Comparing the advantage and the disadvantage of the various methods, we propose a new ad hoc routing protocol performance evaluation method based on wired network: Adding various statistics probe into the application layer, network layer, link layer to collect performance data. In addition, we design and implement a visualization data acquisition and analysis platform, which can collect the performance data for graphical display and analysis and evaluation. This method not only makes up the influence of the sensitive factors such as operating system, system hardware, system design and communication environment, but also solves the problems appeared in in-situ test analysis, e.g. the performance data is not easy to be acquired, the cost is huge and the scene construction is complicated. At last, this paper compares the performance of three typical ad hoc network routing protocols by using the proposed performance data acquisition and evaluation method.
