摘要
分析了差错信道下IEEE802.11b DCF在饱和状态下的吞吐率以及帧长度对吞吐率的影响。研究表明,在一定地误码率下基本访问机制和RTS/CTS两种机制,都存在一个最优帧长使得系统的吞吐率可以达到最大,而且最优值随节点数变化不大。
Throughput of the saturation and the effect of frame length to the throughput are analyzed in the error-prone channel which used IEEE802.11b DCF. It is demonstrated that when BER is given, there is an optimum frame length which can make the throughput reaches its maximum in both basic access mechanism and RTS/CTS mechanism, and the value of the optimum frame length doesn＇t change greatly with the number of the access points.
