A wireless device in an ad hoc network detects other wireless devices
within radio range and establishes synchronization with the detected
wireless devices. The wireless device operates in a power save mode and
wakes up, or turns on, periodically or on demand to implement
discoverability. A received probe request packet or beacon packet
contains information which allows the receiving wireless device to
discover the transmitting wireless device. The wireless device may
operate in a discoverable mode or in an active discovery mode.
