摘要
通过用NS2网络模拟软件构建无线局域网仿真模型,对DCF协议的性能主要是吞吐量性能进行仿真,研究其两种机制下(BAS机制和RTS/CTS机制)业务量、用户数目、帧长与吞吐量的关系,通过分析和测试,并且与理论分析进行比较,得出研究结论,给出协议改进的建议。
In the paper, NS2 network simulation software is used to build wireless Local Area Networks simulation model in order to simulate the performance of DCF Agreement especially the throughput performance. Two mechanisms, both BAS mechanism and RTS/CTS mechanism, are under studied about the relationship between the throughput and the portfolio, the number of users and the length of frame. Through analysis and testing, and comparison of theoretical analysis, we at last draw the conclusion of the study and give out the method to improve it.
