| 摘 要： | 在采用二进制指数退避(BEB)算法的CSMA/CA协议中,针对网络性能随网络规模变化的特性,提出了一种新的网络冲突率分析模型.该模型将网络中的传输站点建立成一个整体的排队网络服务模式,考虑了退避算法中退避次数限制、延时侦测等机制.基于该模型详细地分析了站点在退避计时器结束后,争夺传输时隙的访问方式,推导出网络冲突率的表...

| Abstract: | In the CSMA/CA protocol using the binary exponential backoff algorithm,an effective analytical model of the network collision is proposed for the characteristics of transmission performance with the scale of networks changing.The mechanism for the retry limit of backoff and delay detection is considered,and the whole pattern of queueing networks service for terminals is established in the network,on the basis of which the media access mechanism of the terminal contending for transmission time slot is analyz... |
