CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) is the procedure used by the 802.11 standard to avoid collisions among wireless devices. It is similar to CSMA/CD (Carrier Sense Multiple Access with Collision Detection) used in wired Ethernet, but with the addition of collision avoidance mechanisms. ISM (Industrial, Scientific, and Medical) is a band of radio frequencies used for communication and does not describe a procedure for cooperation among wireless devices. IPSec (Internet Protocol Security) is a protocol used for secure communication over IP networks and is not directly related to wireless device cooperation.
