WebCCA好像应该有2种：CCA-CS，是属于PLCP层的，捕获到能量且能量值高于-82dB后，确定空间忙；CCA-ED，属于协议层，捕获到-62dB信号后，需要判定空间忙，并等待。 修改CCA等级，可以让它对“弱信号”失聪，从而可以在干扰环境中提高吞吐量。2具体实 … WebApr 1, 2024 · In the standard unslotted CSMA/CA, when a node needs to send the data, it cannot execute a CCA till the backoff stage is completed. Therefore, it will result longer delay. While in modified unslotted CSMA/CA, by employing the new backoff procedure, the nodes can do CCA after completing the MB period. As a result, the average delay is …
