| 摘 要： | 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。

| Abstract: | Using renewal and reward theory and Embedded Markov Chain model,a model for TCP performance in Wireless Ad Hoc network was illustrated.The TCP throughput performance achieved by a standard and delayed acknowledge TCP connection over wireless Ad Hoc 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 perform... |
