网络仿真-0.5持续CSMA
- p-持续CSMA协议下,一个用户在发送之前,先侦听信道,若是空闲,就以概率p发送出去,而以q =1-p的概率推迟到下一帧时。如果下一帧时仍是空闲,便再次以概率p发送而以q推迟到再下一帧时。直到发送成功或另外一用户开始发送时为止。若一开始就侦听到信道忙,它就等到下一帧时,然后再开始上述过程。若发生冲突,这等待一随机时间后重新开始。本实验中取q值为0.5。求的是0.5-持续CSMA。 -p-persistent CSMA agreement, a user before sending the
网络仿真-1-持续的CSMA
- 1-持续CSMA协议下,当一个用户要发送数据时,它首先侦听信道,看是否有其他站点在传送。如果信道忙,就持续等待直到信道空闲时,便将数据送出。若发生冲突,就等待一个随机长的时间,然后重新侦听。 对于这种协议,先考虑当前帧i时的前一帧时i-1,得到前一帧时的最后一帧frame0(相对时间最大的帧)的相对时间dt0,然后再在当前帧时查看有哪些帧的相对时间会小于dt0,这些帧若是发送就会与frame0发生冲突,所以这些帧就进入持续等待状态,这些帧并没有发送。再考虑当前帧余下的帧(dt > d
网络仿真-非持续CSMA
- 非持续CSMA 该协议下,用户在发送帧之前,会先侦听信道的状况,如果没有其他站点发送,它就发送。若信道忙,它就等待一个随机的时间后重复以上动作。 对于某一帧而言,信道是否忙,即是看其绝对时间(FRAMETIME*i+dt)的前一帧时内(FRAMETIME*(i-1)+dt ~ FRAMETIME*i+dt)是否存在发送帧。若无则发送,有则等待一随机时间。 -unsustainable under the agreement, users send frames, will first
