基于端到端Ad Hoc网络链路丢失率推测方法研究

可测量性是对Ad Hoc网络进行性能评价和网络管理的基础。文章提出了一种基于端到端多源测量的Ad Hoc网络内部链路丢失率的推测方法,基本思路是:首先利用链路拓扑快照捕获算法获得Ad Hoc网络端到端测量的窗口时间;建立Ad Hoc网络测量模型和链路丢失分析模型;然后在测量窗口时间内,采用多源测量方法实施端到端测量;最后根据采集到的测量样本、网络拓扑中节点间的相关性、链路丢失率分析模型以及数理统计理论推测Ad Hoc网络内部链路丢失率。仿真结果表明:采用基于多源测量的推测方法优于基于单源测量的推测方法,比较适合Ad Hoc网络内部链路性能推测。

A Link Loss Rate Inference Method for Ad Hoc Networks Based on End-to-End Measurement

The measurability is the basis for performance evaluation and management of Ad Hoc networks.We present an interior link loss rate inference algorithm for Ad Hoc networks on the basis of multi-source & multi-destination measurement method.The four steps of this algorithm are as follows:(1) obtain the measurement time window through a link topology snapshot algorithm;(2) build up a measurement model and link loss analysis model for Ad Hoc networks;(3) complete end-to-end multi-source & multi-destination measu...
