1. A discovery method for wireless communication comprising:

  • operating, by a processor, a first node to receive one or more discovery messages from one or more other nodes during a first occurrence of a periodic discovery interval;

    operating, by a processor, the first node to determine a duration of a subsequent occurrence of the periodic discovery interval based on the one or more received discovery messages, said discovery interval including a first time during which said first node listens for discovery messages and a second time during which said first node transmits a discovery message, said determined duration being a time less than or equal to N, wherein N is an initial discovery interval length assigned by an access point; and

    operating, by a processor, the first node to adjust the duration of the subsequent occurrence of the periodic discovery interval based on the determined duration and to reduce a range of count down times used to determine a random starting position of a discovery transmission when the adjusted duration of the subsequent occurrence of the periodic discovery interval is less than N.
