Research on Performance of CSMA Protocol Based on OPNET

摘要:

CSMA协议是无线自组织网络MAC协议中的基本协议,研究其在不同网络条件下的通信性能,对于指导该协议在实际中的具体应用具有重要的作用。基于OPNET网络仿真软件,实现了CSMA协议,设计了不同网络条件下的仿真实验,研究了几个主要的网络参数对CSMA通信性能的影响,为实际网络条件下的CSMA协议性能评估提供参考。

Abstract:

CSMA protocol is a basic protocol in ad hoc MAC protocols. Studying the communication performance of CSMA protocol in different situations is important for guiding its application in practice. In this paper, based on OPNET network simulation software, CSMA protocol was realized and simulation experiments in different situations are designed to study the effects of several key environment parameters on communication performance of CSMA. Results of the experiments were references for the performance evaluation of CSMA in the actual case.
