Patent number: 9769848Abstract: A method and apparatus for a collision-free carrier sense multiple access (CSMA) are provided. The method of a node associated with a beacon enabled carrier sense multiple access (CSMA)-based wireless communication network through an access point (AP) includes receiving a beacon from the AP, the beacon comprising a back-off prime number and a beacon random number, and generating a back-off interval based on the beacon random number, the back-off prime number, a mapped identification (ID) of the node, and a current time slot of a frame of the beacon.
