摘 要: 在分析Ad Hoc网络端到端报文成功传输率乘积模型的同时,从线性角度分析了链路丢失率与路径丢失率之间的不等式关系。在此基础上,提出一种基于端到端单源测量的Ad Hoc网络内部链路丢失率推测方法,解决了Ad Hoc网络内部链路性能的可测量性。仿真结果表明:采用基于乘积模型的丢失率推测方法不仅可以有效地对Ad Hoc网络内部链路丢失率进行推测,而且算法计算量小,适于Ad Hoc网络内部链路性能推测。
关 键 词: 计算机应用;Ad Hoc网络;链路丢失率推测;端到端测量;乘积模型;测量时间窗口

Abstract: This paper first analyzed both the multiplying model of packets successfully transferring rate from end to end and the inequality relation between the loss rate of link and that of path in Ad Hoc networks. Then an interior link loss rate inference algorithm of Ad Hoc networks was presented on the basis of end-to-end measurement to solve the measurability of link performance in Ad Hoc networks. The results of simulation indicate that the loss rate inference algorithm based on multiplying model not only is effective, but also has short computing time, which is very adaptable to interior link performance inference for Ad Hoc networks.
Key words: computer application; Ad Hoc networks; link loss rate inference; end-to-end measurement; multiplying model; measurement time window
