A method of communication includes allocating a portion of a superframe centralized contention based period where the access method is based on directional ALOHA. The centralized contention based period is divided into equal time slots, and each sequential set of N time slots forms a time cycle. During a time cycle, a wireless device listens for requests from other wireless devices while it changes its receiving direction from one time slot to another.
