METHOD FOR HYBRID MEDIUM ACCESS CONTROL FOR VEHICLE COMMUNICATION

摘要

PURPOSE: A method for hybrid medium access control for vehicle communication environment is provided to lower a competition probability between terminals by allowing terminal to dispersive access to slot. CONSTITUTION: A terminal determines whether or not a channel state about a time frame is idle state, if transmitted data frame is generated(S110). The terminal determines whether or not oneself is a slot owner about current slot, if idle state is not set(S160). A first competition window value is set when the terminal is equivalent to slot owner about the current slot(S170).
