Abstract
Disclosed is a method for data communication in a radio network, including calculating an expected value of transmission efficiency of a Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) protocol and an expected value of transmission efficiency of a Slotted ALOHA protocol, comparing the two expected values, switching a mode into the mode of the protocol having the larger expected value from among the expected value of transmission efficiency of the CSMA/CA protocol and the expected value of transmission efficiency of Slotted ALOHA protocol, and broadcasting, to stations (STAs), a message for indicating the STAs to switch a protocol into the protocol having the larger expected value of transmission efficiency, and transmitting data by using the protocol having the larger expected value of transmission efficiency.
