基于嵌入式马氏链的无线自组织网络性能分析

TCP Performance Analysis in Wireless Ad Hoc Network Based on Embedded Markov Chain

利用再生回报过程与嵌入式马尔可夫链,构造了无线自组织网络的TCP吞吐量分析模型。分析了基于IEEE 802.11的3跳网络中,标准TCP连接、具有累计确认功能的TCP连接的吞吐量。结果表明使用累计确认能显著改善无线自组织网络的TCP性能。该模型与分析方法将有助于进一步理解无线自组织网络的TCP性能与吞吐量计算。

Using renewal and reward theory and Embedded Markov Chain model, a model for TCP performance in W＇treless Ad Hoe network was illustrated. The TCP throughput performance achieved by a standard and delayed acknowledge TCP connection over wireless Ad Hoe network was analyzes. The result illustrates that will have a significant throughput if using delayed acknowledgement strategy in TCP connection. The model and the way of analysis will be useful towards the understanding of more complicated scenarios of TCP performance in wireless Ad Hoe network.
