无线信道由于自身的特点,在通信环境较差的情况下其通信质量尤其难以保证。在无线局域网中,通过引入数据包拆分和RTS/CTS会话机制可以对恶劣环境下的通信质量起到改善作用。利用OPNET网络仿真平台,构建了一个集中式网络,设置不同的参数运行仿真,分析包拆分和RTS/CTS会话对网络性能(吞吐量、端到端时延等)产生的影响,为无线局域网的应用开发提供了参考。
Due to its own characteristics, the wireless channel is especially hard to guarantee its communication quality under poor communication environment. In wireless local area networks, communication quality in harsh environments can be improved by introducing packet splitting and RTS / CTS session mechanisms. By using the OPNET network simulation platform, a centralized network is set up, and different parameters are run to simulate the impact of packet splitting and RTS / CTS sessions on the network performance (throughput, end-to-end delay, etc.) for the wireless local area network The application development provides a reference.
