基于OPNET的随机接入协议网络性能研究

Performance Research of Random Access Protocols Network simulation Based on OPNET

针对三种随机接入协议ALOHA、CSMA和CSMA/CD进行了原理介绍和理论分析。利用新兴网络仿真技术OPNET,实现了对三种协议的网络仿真模型的建立,并通过分析信道吞吐量和利用率参数,得出了相关重要得结果和评估。同时说明了利用OPNET能对改进和提高协议的可行性,这也将是以后开发新的随机接入协议的一种思路和方法。

This paper instroduces the principles and analysis the theories of ALOHA,CSMA,CSMA/CD, which belong to random access protocols. By using OPNET simulation platform, the network simulation model of these protocols are constructed. Based on analyzing the simulation results of channel throughout and utilization, the key conclusions and evaluations are drawm..So as to prove the feasibility of using OPNET softwore to improve and amend the protocols, this is a new way to empolder the new random access protocols.
