CSMA/CA (carrier sense multiple access with collision avoidance)
A network access method used on 802.11 wireless networks. In _______, before a node begins to send data it checks the medium. If it detects no transmission activity, it waits a brief, random amount of time, and then sends its transmission. If the node does detect activity, it waits a brief period of time before checking the channel again. ________does not eliminate, but minimizes, the potential for collisions.
