| 摘 要： | 通过电台组网通信在特殊场合具有十分重要的应用价值。电台一般采用半双工方式通信,这种环境下TCP/IP的适用性及其性能值得研究。NS是网络模拟常用的工具,但它本身并不包含半双工链路模型。文中首先讨论在NS网络仿真软件中对半双工链路的建模,进而研究TCP/IP在半双工信道上的性能。模拟实验结果表明:只要解决半双工信道的信息冲突问题,TCP/IP在半双工链路上运行是完全可行的。

| Abstract: | Networking communication with radio station has very important application in some special occasion.Generally,communication mode of radio station is half-duplex.Accordingly,It is desirable to study the applicability and performance of TCP/IP protocol under this condition.The NS is a common network simulator,but there is no half-duplex link model in its component base.In this paper,we first discuss how to set up a half duplex model in NS,and then study the performance of TCP/IP protocol running on half-duplex channel.The results of the simulation experiment show that TCP/IP protocol can absolutely run on a half-duplex channel,if the data collision problem of half-duplex channel could be solved. |
