摘　　要：为了解决CSMA/CD协议中隐接收终端的问题,通过改进该协议,采用两个信道的方式避免隐接收终端的出现,并通过OPNET计算机仿真,从网络模型、节点模型以及进程模型对改进后的CSMA/CD协议进行建模仿真,最后完成对两种协议的性能对比。In order to solve the problem of hidden receiving terminal in CSMA/CD protocol,this paper improves the protocol by using two channels to avoid the appearance of hidden receiving terminal.Through OPNET computer simulation,the improved CSMA/CD protocol is modeled and simulated from network model,node model and process model.Finally,the performance comparison of the two protocols is completed.
