基于端到端Ad Hoc网络链路丢失率推测方法研究
Research on Link Loss Rate Reference Method of Ad Hoc Networks Based on End-to–End Measurement
可测量性是对Ad Hoc网络进行性能评价和网络管理的基础,本文提出一种基于端到端多源测量的Ad Hoc网络内部链路丢失率推测方法,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;在测量窗口时间内,采用多源测量方法实施端到端测量;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。
he measurability is the basis on performance evaluation and management for Ad Hoc networks, this paper presented a interior link loss rate reference algorithm of Ad Hoc network on the basis of End-to-End and multi-sources & multi-destinations measurement method. The main content of this algorithm is as followings: First to obtain the measurement time window through a link topology snapshot algorithm, Second to build up a measurement model and link loss analysis model for Ad Hoc networks, Third to complete End-to-End and multi-sources & multi-destinations measurement, Forth to refer interior link loss rate of Ad Hoc network according to measurement data sample, correlation among mobile nodes in Ad Hoc network topology, link loss analysis model and mathematical statistics theory. Results of simulation indicate that the loss rate reference algorithm based on multi-sources & multi-destinations measurement is not only better than on one-source & multi-destinations measurement, but also the former has short computing time, which is very adaptable to interior link performance reference for Ad Hoc networks.
